The main constitu- ents of hair are sulphur-rich protein order top avana once a day erectile dysfunction caused by spinal cord injury, lipids order 80mg top avana mastercard erectile dysfunction after 80, water buy 80mg top avana with mastercard erectile dysfunction alcohol, melanin, and trace elements (2). The cortex, the main bulk of a fully keratinized hair shaft, contributes almost all the mechanical properties of the hair, including strength and elasticity (2). The cuticle consists of six to eight layers of ﬂattened overlapping cells with their free edges directed upward to the tip of the hair shaft (2). Innermost is the endocuticle, derived from the developing cell cytoplasm contents. The exocu- ticle lies closer to the external surface and comprises three parts: the b-layer, the a-layer, and the epicuticle. The epicuticle is a hydrophobic lipid layer of 18-methyleicosanoic acid on the surface of the ﬁber, or the f-layer. The normal cuticle has a smooth appearance, allowing light reﬂection and limiting fric- tion between the hair shafts. The cuticle may be damaged by frictional forces (brushing, combing or blow-drying) as chemical removal of the f-layer, particularly by oxidation, eliminates the ﬁrst hydrophobic defense and leaves the hair more porous and vulnerable. Cuticle disruption with alkaline chemicals is the ﬁrst step in permanent hair styling (3). If the cuticle is damaged there is little change in the tensile proper- ties of hair. The cortex consists of closely packed spindle-shaped cortical cells rich in keratin ﬁlaments that are oriented parallel to the longitudinal axis of the hair shaft (2), and an amorphous matrix of high sulphur proteins. The intermediate ﬁlament hair keratins (40–60 kDa), comprising 400 to 500 amino acid residues in heptad sequence repeats, form hard keratin polypeptide chains that pair together to form protoﬁlaments, which make up a keratin chain. Cysteine residues in adjacent keratin ﬁlaments form covalent disulphide bonds, which create a strong crosslink between adjacent keratin chains (6). Other weaker bonds link the keratin polypeptide chains together, such as Van der Waal interactions, hydrogen bonds, and coulombic interactions known as salt links (6). The medulla consists of a cortex like framework of spongy keratin supporting thin shells of amorphous material bonding air spaces of variable size. Hair Color Hair color is determined by the melanocytes found only in the matrix area of the follicle at the base of the cortex directly above the follicular papilla. Melanocytes transfer packages of melanin (melanosomes) to the cortical cells during anagen. Pheomelanin, a mutation of eumelanis, is the predominant pig- ment found in blonde or red hair (4). Graying of hair is a normal manifestation of aging and illustrates progressive reduction in melanocyte function. The proportions of eumelanin and phe- omelanin and the total amount of melanin determine the ﬁnal natural color of the hair (5). Human Hair 3 Black and dark brown hair are the prevalent natural hair colors of peoples of all regions, accounting for more than 90% of all human hair. Blonde hair is characterized by low levels of the dark pigment eumelanin and higher levels of the pale pigment pheomelanin. In certain European populations, the occurrence of blonde hair is more frequent, and often remains throughout adulthood, leading to misinter- pretation that blondeness is a uniquely European trait. Based on recent genetic information, it is probable that humans with blonde hair became more numerous in Europe about 10,000 to 11,000 years ago during the last ice age, as a result of Fisherian runaway mechanisms. Prior to this, early Europeans had dark brown hair and dark eyes, as is predominant in the rest of the world. In humans of many ethnicities, lighter hair colors occur naturally as rare mutations, but at such low rates that it is hardly noticeable in most adult populations. Light hair color is commonly seen in children, and is curiously common in children of the Australian Aboriginal population. Bleached blonde hair can be distinguished from natural blonde hair by exposing it to ultraviolet light, as heavily bleached hair will glow, while natural blonde hair will not. There are no comparable data for red hair, but in the areas of obvious frequency (the fringes of Western and Eastern Europe) it is at a maximum of 10%. Controversial estimations of the original occurrence of the red-haired gene at 40,000 years ago are probable. Red hair is associated with the melanocortin-1 receptor, which is found on chromosome 16. When only one copy of the red-hair allele is present, red hair may blend with the other hair color, resulting in different types of red hair including strawberry blonde (red-blonde) and auburn (red-brown). The Record of the Hair The hair shaft records repeated cosmetic practices—the so-called record of the hair (7). Newly emerging hair has properties that are different from those of the hair tips. The more distal part of the hair shaft, particularly the tip, has typically undergone several hundred washes, the application of hot styling implements, and other cosmetic procedures such as bleaching, perma- nent coloring, and perming in addition to normal exposure to the environment. Genetic evidence suggests that Homo sapiens originated only 200,000–250,000 years ago somewhere in the East African savannah. Despite their apparent phenotypic variation, today’s world population is potentially derived from as few as 1,000 to 10,000 individuals. Using average rates of genetic mutation, this population lived at a time that coincided with the massive Toba volcanic disas- ter, which affected global climate, effectively wiped out all other hominids, and devastated Homo sapiens. Descendants of these “modern” humans migrated out of Africa when the climate improved and populated the earth. This is due in the most part to the gross reduction in breeding pairs in the late Pleistocene era. This core of humanity, survived near-extinction and went on to populate the entire world in less than 5000 genera- tions. In less than 100 generations and 2000 years, world population has risen from 3 million to 6 billion. Of the remainder, 14% live in the Americas, 13% in Africa, and 12% in Europe with only 0. Hair form arose from these clans and, as much as skin color, denotes local origins. Despite serial migrations, the original groups have been preserved largely on a regional basis. Bands, which are the simplest form of human society, and still exist (Inuit, indigenous Australians) expanded into clans and sub- sequently tribes. Until the advent of global agriculture some 7,000 ago, genetic lineages were probably tightly maintained. Where and when the emergence of the archetypal hair forms that are described in the literature occurred is not known.
This organism then causes diarrhea by releasing toxins A and B that promote epithelial cell apoptosis order cheap top avana on line erectile dysfunction vitamin shoppe, inflammation trusted 80 mg top avana erectile dysfunction therapy treatment, and secretion of fluid into the colon buy top avana amex erectile dysfunction young age. Nosocomial acquisition of this organism is the most likely reason for patients to harbor it (101). In addition to antibiotic use, risk factors for acquisition include cancer chemotherapy, severity of illness, and duration of hospitalization. The clinical presentation of antibiotic-associated diarrhea and colitis is highly variable, ranging from asymptomatic carriage to septic shock. Time of onset of diarrhea is variable, and diarrhea may develop weeks after using an antibiotic. Most commonly, diarrhea begins within the first week of antibiotic administration. Unusual presentations of this disease include acute abdominal pain (with or without toxic megacolon), fever, or leukocytosis with minimal or no diarrhea (103). On occasion, the presenting feature may be intestinal perforation or septic shock (104). Diagnosis can be made by the less sensitive (*67%) rapid enzyme immunoassay or a more sensitive (*90%) but slower tissue culture assay (106). The finding of pseudomembranes on sigmoidoscopy is also diagnostic and can negate the need for exploratory laparotomy. For many years, oral metronidazole was the agent of choice for most patients requiring treatment. A recent study demonstrated that using oral vancomycin is more effective in seriously ill patients (107). Consequently, it is now recommended that any patient requiring intensive care should be treated with enteral vancomycin if she has leukocytosis! Metronidazole is the only agent that may be efficacious parenterally (108); vancomycin given intravenously is not secreted into the gut. In especially severe cases, patients can be treated with the combination of high-dose intravenous metronidazole and nasogastric or rectal infusions of vancomycin. Although therapy with other agents such as intravenous immunoglobulin and stool enemas has been promulgated, this approach has not been compared directly to other standard regimens. When possible, the intensivist should employ the fewest number of antibiotics necessary, choosing those least likely to interact with other drugs and cause adverse reactions.

You will notice an unusual number of people in that family with the same disease or condition buy top avana 80 mg with visa erectile dysfunction evaluation. Demons Can Enter Through Environment Another extremely common way in which demons invade our lives is through our environments purchase top avana 80mg free shipping impotence natural remedy. A child born to alcoholics may find that although he hates what alcohol has done to his family buy cheap top avana on-line erectile dysfunction medication for high blood pressure, he still finds himself strangely drawn to the cursed liquid. What has happened is the child lives in an atmosphere where that particular spirit is allowed to manifest virtually at will. Unless one is incredibly strong, he will most likely fall victim to the same spirit—even though he hates the effects of the spirit. Or if there is another sinful act, attitude, belief, or behavior, that greatly and consistently manifests itself in that home, the person’s natural and spiritual resistance can be weakened to such a degree that demons may find access. I say involuntary because the person just happens to be raised in this atmosphere. Voluntary environmental demonic invasion happens when we deliberately go to places of strong demonic concentration. It’s as though the environment paralyzes their consciences and draws upon their sexual instincts. How many fornications and adulteries just happened simply because someone was overwhelmed by the strong concentration of demon spirits that hang around such places. There are two of the most beautiful bare breasts in the world saying “Howdy, partner! This happened because he deliberately put himself in a place where there is a strong concentration of demon power. If you are in a place where there is a strong concentration of demon power, get away from it as soon as possible. If this is impractical, or if God has called you to serve in such a place, cry out to Him for strength. Casting out demons, or as it is commonly called, deliverance, is nothing more than a Christian making a demon leave a person through the power of the Holy Spirit. Repeatedly we see Jesus making demons leave by issuing verbal commands to the invading spirits. The below scripture is an excellent summary of Jesus’ deliverance ministry: “When the even [evening] was come, they brought unto him many that were possessed with devils: and he cast out the spirits with his word, and healed all that were sick. There was no religious ceremony, no mystical chants, no use of top secret religious formulas. Several places in the gospels we read that Jesus commanded the disciples to cast out demons. They apparently understood this to mean that they were to follow His example in casting out demons through the use of verbal commands. A clear example of this is given in Luke 10:17, when some disciples returned from an evangelistic trip: “And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name. Another clear example is Acts 16:18: “…But Paul, being grieved, turned and said to the spirit, I command thee in the name of Jesus to come out of her…. Thus, we see conclusively that the routine way to cast out a demon is to simply command it to come out. What May Happen Just Prior to the Command for the Demon to Leave Satan is no fool. Also be aware that demons often manifest their functional nature in their victims when they are in the presence of a Christian who is skilled in deliverance ministry. For instance, if I teach a powerful, insightful message that exposes the way Satan does business, he may manifest himself. The way in which he manifests himself may very well be expressed as the function of the demon. Similarly, a demon of fear or pride may cause the person to exhibit those characteristics. Whatever is the spirit’s predominant nature, that is probably the way in which it will manifest itself when it is disturbed by anointed ministry. For instance, a spirit of fear may become so agitated at a particular sermon that it causes a pain or some other discomfort. What to Expect After the Command is Given Fortunately, the Bible has many examples of what happens when demons are commanded to leave people. In Jesus’ ministry we are given very graphic accounts of what happens when demons are challenged. Since many of the several biblical accounts list similar responses, I will list only those that introduce new material. Sometimes in my meetings I have noticed that most of those delivered manifested screaming demons. Other times the predominant demonic manifestation has been great spontaneous coughing. When the command is given for the demon to come out, you may find that it simply leaves. If you do, you probably will sense its departure in one of several ways: (1) You feel something leave a body part; (2) The demon leaves through screams; (3) The demon leaves through yawns; (4) The demon leaves through tears; (5) The demon leaves through coughs; (6) The demon leaves through vomit or spit. I think Satan uses it to scare others away from seeking or ministering deliverance. When they get in the presence of someone who flows in deliverance ministry, they often panic in fear. Therefore, they do everything they can to convince the victim that the problem is not demonic. If this doesn’t work, and the demon is directly challenged through deliverance ministry, it will pretend to not be there. The demon hopes that the deliverance minister will get discouraged or impatient and stop the challenge. However, if the minister—every Christian is a minister—presses the challenge, the demon may desperately defy the deliverance minister in the hope that he can outlast the minister’s faith, love, and patience. Faith that he actually can cast out this demon; love enough to care to press on to victory; and patience to persist in the face of Satan’s defiance. Often I have been in intense battles with demons that desperately and arrogantly refused to leave their victims. Of course, since I knew that Satan is defeated, and that Christians have authority over him, and since I have learned much about this ministry, these antics didn’t stop me. And, second, I know that the demon’s defiance is being empowered by some undisclosed fact. At a Friday night deliverance service in Atlanta, we ran across an incredibly defiant and arrogant demon. I was busy casting demons out of others, when I noticed that Cynthia, a team member, was being challenged by a demon. She lifted both of her arms and curled her hands as though she was going to claw Cynthia. Without flinching, Cynthia pointed at the demonized lady and firmly said, “You can’t harm me, Satan.
The acupoints are usually located in the interstices in the thick muscles or between the tendons and bones cheap 80mg top avana amex impotence quit smoking. They are connected with both the internal organs and the meridians and collaterals purchase cheap top avana line impotence trials, thus discount 80 mg top avana mastercard erectile dysfunction at age 28, forming a close relationship, known as points-meridians and collaterals-internal organs. According to the theory of meridian and acupoints, the acupoints can be used to treat diseases and keep good health by removing obstruction in the meridian, regulating Qi and blood, reinforcing the deficiency, and reducing the excess. In other words, acupoints are those special somatic positions that can accept a stimulation, reflect a syndrome, and treat diseases (Cheng 1990; Zhang 1990; Qiu and Chen 1992; Zhu 1998; Zhao and Li 2002). Acupuncture, moxibustion, Tuina, and other modalities are performed based on the theory of meridians and acupoints. In the acupuncture literature (Cheng 1990; Zhang 1990; Qiu and Chen 1992; Zhu 1998; Zhao and Li 2002), more than 670 specific sites on the body are considered to be acupoints. A large number of acupoints can be allocated to the point categories with reference to their semantic origin, functional significance, localization, and the links between the separate categories. Furthermore, based on the meridians, these acupoints can be classified into points of the fourteen meridians, extra points, and Ashi points (Qiu and Chen 1992; Zhao and Li 2002; Li 2003). In addition, there are also other therapies developed based on the acupuncture practice. These include electroacupuncture, electrothermal acupuncture, laser acupoint radiation, microwave, acupoint infrared therapy, acupoint magnetic therapy, etc. Clearly, the study on the specificity of the acupoints and meridians helps to elucidate the mechanisms of the acupuncture therapy. Unfortunately, the fundamental nature of the meridians is still unclear, and indeed, there are many controversial results in this field (Xie et al. Till date, the questions regarding the specificity of the acupoints have been explored in several ways: comparing the effects of true points versus the sham points, studying the unique physiological features of the acupoints as well as the anatomical structure at the acupoints, and studying the nerves activated by acupuncture at the acupoints. Acupoints can transport the Qi of the Zang-Fu organs and meridians to the body surface. Thus, when an abnormal function of the meridians and organs occurs, it would lead to the sensation of pain or pressing pain at the relative acupoints (Qiu and Chen 1992; Li 2003). This implies that there are some special relationships between the acupoints and viscera (Qiu and Chen 1992; Chen et al. Several researchers have shown that needling at true points produces marked analgesia, while needling at sham points produces very weak effects (Stacher and Wancura 1975; Chapman et al. Needling at sham points was observed to be effective in 33% 50% of the patients, which is similar to the effect of placebo analgesia, while needling at acupoints was found to be effective in 55% 85% of the cases. Using animal models (Pomeranz and Chiu 1976; Chan and Fung 1975; Fung and Chan 1975; Cheng and Pomeranz 1980; Takashige 1985; Toda and Ichioka 1978; Fung and Chan 1976; Liao et al. These results suggest that different acupoints on the same meridian may activate similar areas of the brain. In addition, acupoints that are commonly used in clinical practice might affect a greater extent of the cortical areas than the uncommonly used acupoints. There have been a number of reports stating that the skin resistance (impedance) over acupoints is lower than that of the surrounding skin (Zeng 1958; Becker and Reichmanis 1976; McCarroll and Rowley 1979; Chan 1984; Xu 1987; Lu 1987; Chen et al. However, in the studies claiming the unique properties of the acupoints, this value was found to be 50,000 ohms at the acupoints. It is further claimed that during the course of a disease of particular organs, the resistances at the acupoints become abnormally low (even lower than the usual low resistance at the acupoints) (Hu 1987; Gao 1987). Some reports showed a potential difference of 5 mV or more in the positive direction between the acupoints and the neighboring skin (Zeng 1958; Tseng and Chang 1958). In addition, Jaffe and Barker (1982) also showed that the human skin has a resting potential across its epidermal layer from 20 mV to 90 mV (outside negative, inside positive). From these studies, one can speculate that acupoints with low resistance tend to short- circuit this battery across the skin, and consequently, give rise to a source of current in a source-sink map of the skin. Some studies (Xu 1987) also demonstrated that the regeneration of the amputated amphibian limbs was enhanced by the application of the electric fields (and currents) in the direction of the negative pole. However, some scientists and clinicians are quite skeptical about the entire skin resistance phenomenon and most of the voltage measurements (Summarized by Stux and Pomeranz in 1988), because the measurements were not made according to the established biophysical practice. In particular, the electrochemical potential artifacts produced at the electrode-to-skin interface are observed to be high when compared with the millivolts being generated by the body. Furthermore, neither the published reports nor the clinical anecdotal observations were based on properly conducted studies. Hence, it seems unclear whether the low resistance or high voltage could be of any physiological significance to acupoints. There is a possibitity that the presence of a large nerve, emerging from deep tissues to more superficial layers, induce changes in the skin resistance. Unfortunately, no unique structures have been found for the acupoints in most of the histological studies of the skin and subcutaneous structures. However, several authors have made the astute observation that the anatomical structures of acupoints have some special particularities. Some investigators reported that the acupoints are motor points, at which the nerve enters the muscle and approximates, but are not identical to the end-plate zone of the motor nerve endings (Gunn and Milbrandt 1977, 1980; Dung 1984). Hence, needling at these acupoints is very effective in influencing the sympathetic activity. Some researchers, through cross-sectional dissection, observed that 55% of the acupoints on the body were located just at the cluster of the muscles, and those muscles and fascias at the acupoints were considerably thick and centralized (Liu et al. The muscles are observed to be wrapped around by superficial and deep fascias, and must be penetrated by the needles permeating the fascias. Therefore, it was proposed that the acupoints were just trigger points of the muscles. For example, Melzack and Wall (1965) and Melzack (1975) found that 71% of the acupoints correspond to trigger points. On the other hand, some studies suggest that connective tissues are the structural basis of the acupoints and meridians, as well as responsible for inducing the 37 Acupuncture Therapy of Neurological Diseases: A Neurobiological View sensation of “De-Qi” of acupuncture. In the hypodermis, the connective tissue fibers circling the puncturing pore demonstrated a whirly form. Furthermore, in the muscle layer, the connective tissue fibers of the endomysium circled the pore, and the relative muscle fibers were twisted and dislocated. Hence, the authors regarded that the various needling-sensitive tissues and structures were simultaneously stimulated by the twirling needle force, with the connective tissue acting as a mediator, which might be the possible biological basis of needling sensation and its complexity. In addition, Langevin et al (2001, 2002) also hypothesized that needle grasp is owing to the mechanical coupling between the needle and the connective tissue, with winding of the tissue around the needle during the needle rotation, and that needle manipulation transmits a mechanical signal to the connective tissue cells via mechanotransduction. In addition, some studies suggest that the mast cells under the acupoints play a key role in the stimulation of local tissues and generation of acupuncture signal (Yang and Wang 1986; Zhu and Xu 1990; Deng et al. Particularly, the mast cells were found to be distributed extensively in the connective tissues of the whole body, and were especially clustered in the positions that receive more external irritants, such as subcutaneous tissue and submucous layers. Moreover, more mast cells were observed to be distributed at the acupoints than at non-acupoints, and were usually distributed among the small vessels and nerve tract along their meridian course.
