Abstract
BACKGROUND Findings from family and twin studies support a genetic contribution to the development of sexual orientation in men. However, previous studies have yielded conflicting evidence for linkage to chromosome Xq28. METHOD We conducted a genome-wide linkage scan on 409 independent pairs of homosexual brothers (908 analyzed individuals in 384 families), by far the largest study of its kind to date. RESULTS We identified two regions of linkage: the pericentromeric region on chromosome 8 (maximum two-point LOD = 4.08, maximum multipoint LOD = 2.59), which overlaps with the second strongest region from a previous separate linkage scan of 155 brother pairs; and Xq28 (maximum two-point LOD = 2.99, maximum multipoint LOD = 2.76), which was also implicated in prior research. CONCLUSIONS Results, especially in the context of past studies, support the existence of genes on pericentromeric chromosome 8 and chromosome Xq28 influencing development of male sexual orientation.

Abstract
Human auditory nerve afferents consist of two separate systems; one is represented by the large type I cells innervating the inner hair cells and the other one by the small type II cells innervating the outer hair cells. Type I spiral ganglion neurons (SGNs) constitute 96% of the afferent nerve population and, in contrast to other mammals, their soma and pre- and post-somatic segments are unmyelinated. Type II nerve soma and fibers are unmyelinated. Histopathology and clinical experience imply that human SGNs can persist electrically excitable without dendrites, thus lacking connection to the organ of Corti. The biological background to this phenomenon remains elusive. We analyzed the pre- and post-somatic segments of the type I human SGNs using immunohistochemistry and transmission electron microscopy (TEM) in normal and pathological conditions. These segments were found surrounded by non-myelinated Schwann cells (NMSCs) showing strong intracellular expression of laminin-β2/collagen IV. These cells also bordered the perikaryal entry zone and disclosed surface rugosities outlined by a folded basement membrane (BM) expressing laminin-β2 and collagen IV. It is presumed that human large SGNs are demarcated by three cell categories: (a) myelinated Schwann cells, (b) NMSCs and (c) satellite glial cells (SGCs). Their BMs express laminin-β2/collagen IV and reaches the BM of the sensory epithelium at the habenula perforata. We speculate that the NMSCs protect SGNs from further degeneration following dendrite loss. It may give further explanation why SGNs can persist as electrically excitable monopolar cells even after long-time deafness, a blessing for the deaf treated with cochlear implantation.

Abstract
AIM It is unknown how the heart distinguishes various overloads, such as exercise or hypertension, causing either physiological or pathological hypertrophy. We hypothesize that alpha-calcitonin-gene-related peptide (αCGRP), known to be released from contracting skeletal muscles, is key at this remodelling. METHODS The hypertrophic effect of αCGRP was measured in vitro (cultured cardiac myocytes) and in vivo (magnetic resonance imaging) in mice. Exercise performance was assessed by determination of maximum oxygen consumption and time to exhaustion. Cardiac phenotype was defined by transcriptional analysis, cardiac histology and morphometry. Finally, we measured spontaneous activity, body fat content, blood volume, haemoglobin mass and skeletal muscle capillarization and fibre composition. RESULTS While αCGRP exposure yielded larger cultured cardiac myocytes, exercise-induced heart hypertrophy was completely abrogated by treatment with the peptide antagonist CGRP(8-37). Exercise performance was attenuated in αCGRP(-/-) mice or CGRP(8-37) treated wild-type mice but improved in animals with higher density of cardiac CGRP receptors (CLR-tg). Spontaneous activity, body fat content, blood volume, haemoglobin mass, muscle capillarization and fibre composition were unaffected, whereas heart index and ventricular myocyte volume were reduced in αCGRP(-/-) mice and elevated in CLR-tg. Transcriptional changes seen in αCGRP(-/-) (but not CLR-tg) hearts resembled maladaptive cardiac phenotype. CONCLUSIONS Alpha-calcitonin-gene-related peptide released by skeletal muscles during exercise is a hitherto unrecognized effector directing the strained heart into physiological instead of pathological adaptation. Thus, αCGRP agonists might be beneficial in heart failure patients.

Abstract
AIMS Little is known about the incidence of paroxysmal atrial tachycardias (PAT) in patients with heart failure (HF). The availability of cardiac resynchronization therapy (CRT) devices with extended diagnostics for AT enables continuous monitoring of PAT episodes. The aim of the study was to assess the incidence over time of PAT in HF patients treated with CRT. METHODS AND RESULTS Consecutive patients in NYHA functional class III or IV despite optimal drug therapy, QRS duration > or = 130 ms, left ventricular ejection fraction < or = 35%, and left ventricular end-diastolic dimension > or = 55 mm were eligible for enrolment. Patients with permanent or persistent atrial fibrillation (AF) were not included in the study. The first follow-up examination was performed 2 weeks after implantation, to optimize atrial sensing and CRT. Subsequent follow-up examinations were carried out 15 and 28 weeks after implantation, to collect the telemetric data. A total of 173 patients (67 +/- 11 years, M 116) were enrolled. Complete arrhythmia monitoring data were available from 120 patients over a mean follow-up of 183 +/- 23 days. Atrial tachycardia episodes were detected through telemetry in 25 of 120 patients (21%) during at least one follow-up examination. Atrial tachycardia episodes were recorded in 29 and 17% (P = NS) of patients with and without previous history of AF, respectively. CONCLUSION More than 20% of the overall HF patient population treated with CRT suffer PAT episodes. Paroxysmal atrial tachycardia may interfere with response to CRT. Therefore, telemetric data may be relevant to drive the appropriate therapy in each patient.

Abstract
Primary ciliary dyskinesia (PCD) is an autosomal recessive inherited disease characterized by abnormal ciliary motion and impaired mucociliary clearance. The prevalence of PCD is approximately 1 : 15 000 - 1 : 20 000 in live births. Cilia dysfunction is also implicated in a wider spectrum of diseases due to impaired organ genesis and body symmetry. Cilia are highly conserved in animals and show complex structures containing more than 250 proteins for their formation. Recent studies have begun to locate the PCD genes in the genome and characterize functional mutations. Specific diagnosis of the ciliary dysfunction requires physiological measurements as well as light- and electron microscopy. Abnormalities in ciliary motion and ultrastructural studies can be performed with nasal mucosal epithelium.

Abstract
BACKGROUND/AIMS Among the causes related to the development or perpetuation and aggravation of dry eye disease, oxidative reactions may have a role in the pathogenesis of this disorder. Antioxidants, such as iodide, have shown a strong effect in preventing the oxidative damage to constituents of the anterior part of the eye. In this clinical trial the effectiveness of iodide iontophoresis and iodide application without current in moderate to severe dry eye patients was compared. METHODS 16 patients were treated with iodide iontophoresis and 12 patients with iodide application without current for 10 days. Subjective improvement, frequency of artificial tear application, tear function parameters (break up time, Schirmer test without local anaesthesia), vital staining (fluorescein and rose bengal staining) as well as impression cytology of the bulbar conjunctiva were evaluated before treatment, 1 week, 1 month, and 3 months after treatment. RESULTS A reduction in subjective symptoms, frequency of artificial tear substitute application, and an improvement in certain tear film and ocular surface factors could be observed in both groups. A stronger positive influence was seen after application of iodide with current (iontophoresis), as observed in a distinct improvement in break up time, fluorescein and rose bengal staining, and in a longer duration of this effect compared with the non-current group. No significant change in Schirmer test results and impression cytology were observed in both groups. CONCLUSIONS Iodide iontophoresis has been demonstrated to be a safe and well tolerated method of improving subjective and objective dry eye factors in patients with ocular surface disease.

Abstract
In the trauma register of the German society of traumatology until now 5353 patients have been analysed. The mean age was 38.5 years, the proportion of blunt injuries was 94.3%. The mean ISS was 24.8%, the emergency doctor arrived in the middle 22.4 minutes after the accident. The stay of the emergency doctor lasted 32.9 minutes and the transport from the place of accident to the hospital took 18.3 minutes. The rate of intubation through the emergency doctor was 58.3%. The mean stay at hospital was 31.1 days, at the intensive car unit 13.1 days with a mean time of 8.7 days artificial respiration. In comparing the years we saw an improvement of outcome throughout all participating hospitals. Future aims of the trauma register are to increase the quality of life after trauma, to guarantee an adequate quality of treatment, to analyse costs and to include all German hospitals in the trauma register.

Abstract
Questions as to the critical stress factor and primary targets of cold ischemia/reperfusion (CIR) injury were addressed by comparing mitochondrial defects caused by (1) CIR injury and (2) intracellular Ca2+ overload. CIR was simulated in transformed human umbilical vein endothelial cell cultures (tEC) by 8 h cold anoxia in University of Wisconsin solution and reoxygenation at 37 degrees C. Intracellular Ca2+ concentrations were changed by permeabilization of suspended cells with digitonin in culture medium (RPMI, 0.4 mM Ca2+). Binding of free Ca2+ by ethylene glycol-bis(beta-aminoethylether)-N,N,N',N'-tetraacetic acid in RPMI or mitochondrial incubation medium served as controls. Extracellular Ca2+ protected the cell membrane against permeabilization. Mitochondrial functions were determined before and after permeabilization of the cell membrane. After CIR, mitochondrial respiratory capacity declined, but oxygen consumption remained coupled to adenosine triphosphate (ATP) production. In contrast, Ca2+ overload caused uncoupling of mitochondrial respiration. High intracellular Ca2+ overload, therefore, does not reproduce cold ischemia/reperfusion injury in endothelial cells.

Abstract
BACKGROUND Increased UV radiation and ozone exposure may cause "dry eyes of environmental origin", if the normal anti-oxidative capacity of the tear film can no longer cope with the oxidative stress. The use of artificial tears with an adequate anti-oxidative effect may be beneficial in the treatment of dry eyes caused by environmental factors. METHODS The anti-oxidative capacity of various commercial artificial tear preparations was determined with a modified TRAP procedure. The two preparations with the strongest anti-oxidative effect were then examined for their protective effects against UV or ozone exposure in a hyaluronate model. RESULTS Of 19 artificial tear preparations tested, only 6 showed strong to moderate anti-oxidative effects. All others were at best weakly anti-oxidative or had no anti-oxidative effect at all. Some of them even acted as oxidants. Although the two most strongly anti-oxidative preparations performed somewhat differently on UV and ozone exposure, they were both found to be highly protective against these important oxidative stress factors. CONCLUSIONS The anti-oxidative capacity of artificial tear preparations varies widely. While some are strong anti-oxidants, others are less active or even act as oxidants. If the carefully elicited history of patients with dry eyes suggests that noxious environmental factors may be causally involved, artificial tears which are not just lubricants or contain wetting agents, but act as anti-oxidants, should be chosen for treatment from the many commercially available preparations. Such an etiology-oriented concept would probably improve the success rate of treatment for dry eyes.

Abstract
The internal fixation of fractures of shaft bones was spread out by a group of surgeons working together with Prevot. The principle of this method is a three point load carrying paragraph sign(entry point, height of fracture and cancellous bone of the metaphysis of the opposite fracture part). From 1996 to 1999 86 children with fractures of the humerus, the fore-arm and the femur were operated in the technique of intramedullary nailing. The fractures affected the humerus to 3.5 %, the fore-arm to 65.1 % and the femoral shaft to 31.4 %. The postoperative duration of stay in hospital after internal fixation of the fore-arm in the proximal and middle third lasted 7.2 days, the duration of immobilisation in a cast took 13.7 days. 96 % of the patients showed very good and good results after operation. The average stay in hospital for patients with femoral shaft fractures was 14.4 days. 17 weeks after operation the intramedullary nails were removed. At the time of first full weight bearing the legs showed an average shortening of 1.2 cm. The fractures of the humerus healed without any restriction of movements. Internal fixation is a minimal invasive operation technique with low risks and small operating trauma. Due to the stability a early mobilisation is possible. The reported results in the literature are all good. The only problem can be caused by too long nails irritating the skin.

Abstract
BACKGROUND Protection of vascular endothelium is a critical factor in organ preservation for transplantation. This study aims at a morphological assessment of endothelial cell injury in a comparison of storage solutions, using a cell culture model of cold preservation and rewarming. MATERIALS AND METHODS Human umbilical vein endothelial cells (HUVEC) were cultured in monolayer and exposed to hypothermic storage in University of Wisconsin (UW), histidine-tryptophane-ketoglutarate (HTK), and EuroCollins solutions for 6 h and subsequent rewarming for 30 min or 6 h. Alterations of subcellular structures and cell-cell contacts were analyzed by transmission electron microscopy (TEM) and light microscopic assessment after actin and nuclear staining. RESULTS Structural alterations of mitochondria, endoplasmic reticulum, nuclei, and cytoskeletal fibers as well as disruption of intercellular contacts were found after cold storage in HTK and EuroCollins solutions. In contrast, storage in UW solution resulted in minimum changes of stress fibers only. A rapid rearrangement of structural alterations was achieved during rewarming in cell culture medium in all experimental groups. CONCLUSIONS Preservation of endothelial cell structure is best achieved by UW solution. Ultrastructural cell damage is a direct consequence of hypothermic storage and is fully reversible during rewarming after short storage times.

Abstract
BACKGROUND The precorneal tear film is of decisive importance for the optical quality of the cornea. Poor stability of this film causes not only dry eye symptoms, but also has negative effects on optical functions of the eye, as previous studies on visual acuity, field test performance and contrast sensitivity have shown. METHODS 60 patients with dry eyes randomized into 2 groups of 30 underwent color vision testing with the Lanthony Desaturated 15 Hue test before and after instillation of artificial tear (test group) or physiological saline (control group) drops. RESULTS The improvement in color discrimination in the group given artificial tear treatment was found to be slightly better than in the saline group but in both groups this improvement was not of statistical significance. CONCLUSION Even though an unstable tear film adversely affects the optics of the eye and even mildly degraded optics can affect spatial visual tasks, color discrimination performance on tasks such as the Lanthony D-15 test does not appear to be markedly impaired.

Abstract
The oxygen affinity of the enzyme system involved in mitochondrial respiration indicates, in relation to intracellular oxygen levels and interpreted with the aid of flux control analysis, a significant role of oxygen supply in limiting maximum exercise. This implies that the flux control coefficient of mitochondria is not excessively high, based on a capacity of mitochondrial oxygen consumption that is slightly higher than the capacity for oxygen supply through the respiratory cascade. Close matching of the capacities and distribution of flux control is consistent with the concept of symmorphosis. Within the respiratory chain, however, the large excess capacity of cytochrome c oxidase, COX, appears to be inconsistent with the economic design of the respiratory cascade. To address this apparent discrepancy, we used three model systems: cultured endothelial cells and mitochondria isolated from heart and liver. Intracellular oxygen gradients increase with oxygen flux, explaining part of the observed decrease in oxygen affinity with increasing metabolic rate in cells. In addition, mitochondrial oxygen affinities decrease from the resting to the active state. The oxygen affinity in the active ADP-stimulated state is higher in mitochondria from heart than in those from liver, in direct relationship to the higher excess capacity of COX in heart. This yields, in turn, a lower turnover rate of COX even at maximum flux through the respiratory chain, which is necessary to prevent a large decrease in oxygen affinity in the active state. Up-regulation of oxygen affinity provides a functional explanation of the excess capacity of COX. The concept of symmorphosis, a matching of capacities in the respiratory cascade, is therefore complemented by 'synkinetic' considerations on optimum enzyme ratios in the respiratory chain. Accordingly, enzymatic capacities are matched in terms of optimum ratios, rather than equal levels, to meet the specific kinetic and thermodynamic demands set by the low-oxygen environment in the cell.

Abstract
Iodine distribution was studied in isolated porcine eyes after iontophoresis using 131I-labelled solutions and chemical methods. After a 15-min treatment with a therapeutically used iodine brine, the iodine content in the ocular tissues showed the following rank order: cornea > retina > vitreous body > anterior chamber fluid > lens. Replacement of the brine by 0.15 M NaI increased the uptake values in a different way, but the same rank order was maintained. The increase was highest in the cornea (5.6-fold) and only about 2-fold in the lens, nevertheless approaching now the level of 10(-4) M, a concentration which was regarded as being optimal for the antioxidant effect of I-. Among the other eye components, the relatively high iodine enrichment of the retina was remarkable. The data are discussed with respect to a possible protective, antioxidative and OH-scavenging efficacy of I- and to previous results in the literature concerning iodine uptake in ocular tissues.

Abstract
The relationship between the activity of the antioxidant defense enzyme glutathione peroxidase (GSH-PX) and the degree of cataract (lens opacity) was examined in 14 Emory mice at the age of 2, 7 and 10 months. Significant decreases in specific GSH-PX activity (mU/mg wet tissue) in the lens as well as in the residual eye tissue were found between 2 and 10 months of age, showing a highly significant correlation of this decrease (r = 0.590, p approximately 0.001) with the increasing degree of turbidity of the lenses. The results are discussed with regard to the changes of antioxidant mechanisms during cataractogenesis and aging. The role of the maintenance of an optimal level of GSH-PX and other well-known antioxidants (enzymes, vitamins, trace elements including iodide) for a delay of cataractogenesis is pointed out.

Abstract
Poor stability of the precorneal tear film causes dry eye symptoms and has detrimental effects on the optical function of the eye. In 50 patients with dry eyes the local instillation of artificial tears significantly improved contrast sensitivity (P < 0.001), using the Vision Contrast Test System 6500. In the untreated eyes no significant changes were found to occur (P = 0.56).

Abstract
Yellow filter glasses, often sold as "antifog" or "safety" glasses at department stores and other retail outlets, are claimed to improve contrast sensitivity and the yield of visually perceived objects, particularly under poor conditions (e.g., fog, rain and twilight), by enhancing contrast. These claims were tested in 15 healthy subjects (30 eyes) aged 26 to 58 (mean 42.5) years with the Vision Contrast Test System (VCTS 6500), first with and then without yellow filter glasses. Testing was done with commercial antifog glasses and frame-mounted, hand-held filter glasses of CR (Columbia resin) 39 quality with a yellow tint made by an optician. Contrast sensitivity was found to be significantly improved with yellow filter glasses (p less than 0.0001). The use of yellow filter glasses may safely be recommended to patients who report subjective improvement in contrast vision with such glasses.

Abstract
The optical function of the eye critically depends on the presence of an intact precorneal tear film. Abnormalities of the tear film such as those occurring in the dry eye syndrome or in otherwise irritated eyes may interfere with vision. In 30 patients with dry eyes artificial tears were found to produce statistically significant improvement of vision (p less than 0.001) while no significant changes were seen in the untreated partner eyes. Static perimetry in another 30 patients using the 'macular programme' of the automatic Humphrey 620 perimeter showed artificial tears to increase mean thresholds significantly (p less than 0.001) whereas no significant differences were seen in the untreated partner eyes.

Abstract
After a cure with iodine in Bad Hall (Upper Austria), patients with age-related maculopathy repeatedly reported improvement in visual power: the picture seen seems to be clearer on the whole or more distinct. These statements were checked in 50 patients with beginning age-related macula degeneration ('dry form') using the 'Vision Contrast test system (VCTS 6500)'. The analysis of the results showed that there is indeed a statistically highly significant improvement in contrast sensitivity after the cure (p < 0.0001). The spontaneous observations of the patients were therefore confirmed by the study.

Abstract
Cataract development was studied in two groups of Emory mice by periodical biomicroscopic examinations (beginning at 5 weeks of age) and by a final evaluation of water-soluble SH groups in the lenses. The experimental group was given 256 micrograms iodide/kg body weight with the drinking water throughout the study. The untreated control group received tap water. Iodide treatment induced a delay of cataract formation, resulting in a significant reduction of the time to progress from cataract degree 1 to degree 2 (iodide-treated group 12.8 +/- 1.7 weeks, untreated group 9.9 +/- 1.0 weeks; p less than 0.025). A still significant difference in the degree of cataract was also found between the two groups at week 47 of age. No difference was found in the content of water-soluble SH groups. The results are discussed in relation to the known antioxidant and .OH-scavenging effect of iodide and to the oxidative changes in the lens occurring during progression of cataract development.

Abstract
Disturbances of the lipid composition can, like mucin or fluid deficiency, cause 'dry eye'. The substitution of the lipids of the tear fluid has previously been unsatisfactory since eye ointments containing fats can lead to a considerable deterioration of the visual acuity due to the film of ointment resulting from an irregular spreading behavior. We proposed the introduction of physiological lipids that are normally present in tear fluid, such as phospholipids, saturated and unsaturated fatty acids and triglycerides, to provide lipid-containing eye drops. These best correspond to 'natural tears' and, due to the small size of the lipid particles, avoid a disturbance of the spreading behavior of the lipid layer. With lipid-containing eye drops of this kind, we carried out the following examinations: inquiry of patients' symptoms based on a standardized interview; Schirmer test under local anesthesia; break-up time (BUT); biomicroscopic evaluation of the lipid film, and stability tests as pH, gas chromatographic analysis of the fatty acid pattern and thin-layer chromatographic analysis of the lipid pattern. Schirmer test, BUT measurement and questioning about symptoms were undertaken after 1 week and then again after 3 weeks of treatment. All three parameters finally showed an improvement with a high statistical significance (p less than 0.001). The stability tests have shown that pH, lipid particle size, fatty acid and lipid composition of the examined lipid-containing eye drops were nearly unchanged till 4 months after preparation.

Abstract
After taking a cure with iodine treatments in Bad Hall (Upper Austria), patients with eye diseases repeatedly report improvements in their color vision. They state that colors are once again "more saturated, richer, and more distinct." These statements were checked using the Farnsworth Panel D-15 dicotomous test and the Lanthony desaturated 15 Hue test. The analysis of the results showed that there is indeed a statistically significant improvement in color vision after the cure. The spontaneous observations of the patients were therefore confirmed by the study.

Abstract
Deficient lacrimal secretion as a consequence of systemic drug therapy has been reported after the use of phenothiazines, antihistaminics, psychotropic drugs, anesthetics, diuretics, beta-blocking agents, ganglion blockers etc. But topical application of beta-blocking eye drops may also decrease tear production. The study reported here proves that tear production is also decreased if one drop of "Mydriaticum Roche" eye drops is applied. This effect was observed especially in patients who had "normal basic tear production" prior to treatment; however, "Mydriaticum Roche" did not cause a further decrease in tear production during Schirmer's test when the basic tear secretion level was already very low. Therefore, in order to avoid "false positive" results Schirmer's test should always be performed before instillation of atropine-active eye drops such as "Mydriaticum Roche".

Abstract
Attempts were made (1) to develop an appropriate method for producing standardizable and reproducible experimental opacities of the cornea of rats and (2) to study quantitatively the course and intensity of the healing process of these corneal wounds. The right cornea of rats was cauterized by drops of 1.5 N HC1 over 30 s; the left one served as a control. The spontaneous course of wound healing, as well as the possible effect on this process of spray treatment with iodine brine or, for comparative purposes, with isotonic NaCl, was studied for 10 consecutive days by measuring the 24-h incorporation of 14C-labelled proline as a measure of de novo collagen synthesis. Spray treatment (1) abolishes the transient inhibition of proline incorporation observed in the unsprayed cornea on the first day after injury and (2) significantly advances the maximum collagen synthesis rate from day 3-4 to day 2 after the wound occurred. The position and magnitude of the 14C-proline incorporation peak are considered to be useful parameters for estimating corneal wound healing activity and its alteration by various agents. However, in this experimental design, it could not be proved that iodine has a specific effect.

Abstract
The relatively high variation of the lysozyme content in tear fluid, observed during investigations to determine standard values, led the authors to assume that diluting effects occur during tear sampling. Compensation of these presumed effects by means of an anorganic cation results in a significant decrease in variation. However, homogeneity of the data, necessary for calculating standard values, is still not achieved.

Abstract
A 50-year-old woman presented with a tumorlike growth of the tarsal conjunctiva of the left upper lid. The historical examination revealed an amyloid tumor. It was possible to remove most of the tumor surgically. The resection was followed by almost complete regression of the remnants.
