Sukrit Ranjan, Robin Wordsworth, Dimitar D Sasselov
Recent findings suggest that Mars may have been a clement environment for the emergence of life and may even have compared favorably to Earth in this regard. These findings have revived interest in the hypothesis that prebiotically important molecules or even nascent life may have formed on Mars and been transferred to Earth. UV light plays a key role in prebiotic chemistry. Characterizing the early martian surface UV environment is key to understanding how Mars compares to Earth as a venue for prebiotic chemistry...

INTRODUCTION: A rapid increase in awareness of androgen deficiency has led to substantial increases in prescribing of testosterone therapy (TTh), with benefits of improvements in mood, libido, bone density, muscle mass, body composition, energy, and cognition. However, TTh can be limited by its side effects, particularly erythrocytosis. This review examines the literature on testosterone-induced erythrocytosis and polycythemia. AIM: To review the available literature on testosterone-induced erythrocytosis, discuss possible mechanisms for pathophysiology, determine the significance of formulation, and elucidate potential thromboembolic risk...

Bacteria use cell surface proteins and secreted proteins to interact with host tissues. Several dozen previously published proteomics studies have identified cell surface proteins for pathogens. In this issue, Celebioglu and Svensson (Proteomics 2017, XXX, XXX-XXX) use 2-D gel electrophoresis and mass spectrometry to identify secreted and cell surface proteins of a commensual gut bacterium, Lactobacillus acidophilus NCFM. Some of the proteins are known to have functions in the cytoplasm, and their presence on the cell surface suggests they might be moonlighting proteins...

Cerebrovascular reactivity (CVR) is the cerebral hemodynamic response to a vasoactive substance. Breath-hold (BH) induced CVR has the advantage of being non-invasive and easy to implement during magnetic resonance imaging (MRI). We systematically reviewed the literature regarding MRI measurement of BH induced CVR. The literature was searched using MEDLINE with the search terms breath-hold; and MRI or cerebrovascular reactivity. The search yielded 2244 results and 54 articles were included. Between-group comparisons have found that CVR was higher among healthy controls than patients with various pathologies (e...

Turner syndrome (TS), characterized by short stature and premature ovarian failure, is caused by chromosomal aberrations with total or partial loss of one of the two X chromosomes. Spontaneous puberty, menarche, and pregnancy occur in some patients depending on the abnormality of the X. Moreover, spontaneous pregnancy is uncommon (<0.5%) for TS with 45,X monosomy. Among TS patients, 45,X/47,XXX karyotype is extremely rare. Previous reports have demonstrated that TS with 45,X/47,XXX is less severe than common TS due to higher occurrence of puberty (83%), menarche (57-67%), and fertility (14%) and lower occurrence of congenital anomalies (<5%)...

BACKGROUND: Cognitive-affective factors contribute to female sexual dysfunctions, defined as clinically significant difficulties in the ability to respond sexually or to experience sexual pleasure. Automatic thoughts and affect presented during sexual activity are acknowledged as maintenance factors for these difficulties. However, there is a lack of studies on the influence of these cognitive-affective dimensions regarding female orgasm. AIM: To assess the role of automatic thoughts and affect during sexual activity in predicting female orgasm occurrence and to investigate the mediator role of these variables in the relation between sexual activity and orgasm occurrence...

INTRODUCTION: No surgical technique is reported to be the best option for gender-affirmation surgery (GAS) of the genitalia in transmen. Although patients' preferences are central when choosing a surgical technique, no studies have evaluated this factor. AIM: To investigate transmen's priorities and preferences regarding GAS of the genitalia. METHODS: From November 2015 to March 2016, 54 transmen with the diagnosis of gender dysphoria who were referred to Sahlgrenska University Hospital for discussion of therapeutic steps (surgery and hormonal treatments) were asked to complete a questionnaire on different attributes achievable with GAS, such as sexual and urinary function and appearance...

This report describes a pregnancy with a triploid fetus identified from a scan for anomalies at 18 weeks and confirmed by amniocentesis. A 29-year-old, primigravida woman was referred to our clinic for genetic counseling at 18 weeks of gestation because of a mild oligohydramnios due to amniotic fluid index (AFI) less than the fifth percentile in her 18th week. The woman underwent amniocentesis, which revealed a karyotype of 69,XXX. There was no consanguinity in this family. In postmortem evaluation, we encountered a hydrocephalic fetus with an aberrant skull shape, including dysplastic calvaria with large posterior fontanel, marked intrauterine growth retardation (IUGR) in addition to syndactyly of third and fourth fingers, exophthalmia, cleft palate, low set malformed ears, micrognathia and club foot...

Multiple functional attributes of glucose-monitoring neurons in the medial orbitofrontal (ventrolateral prefrontal) cortex. NEUROSCI BIOBEHAV REV 73(1) XXX-XXX, 2017.- Special chemosensory cells, the glucose-monitoring (GM) neurons, reportedly involved in the central feeding control, exist in the medial orbitofrontal (ventrolateral prefrontal) cortex (mVLPFC). Electrophysiological, metabolic and behavioral studies reveal complex functional attributes of these cells and raise their homeostatic significance. Single neuron recordings, by means of the multibarreled microelectrophoretic technique, elucidate differential sensitivities of limbic forebrain neurons in the rat and the rhesus monkey to glucose and other chemicals, whereas gustatory stimulations demonstrate their distinct taste responsiveness...

INTRODUCTION: Peyronie's disease (PD) is a connective tissue disorder resulting in the abnormal accumulation of type I to III collagen, fibrin, and disorganized elastic fibers in the tunica albuginea of the penis. Many medical and non-pharmacologic modalities have been used in the treatment of PD; however, these approaches have proved largely ineffective, with surgery being the only definitive treatment. Intralesional injection of collagenase Clostridium histolyticum (CCH) has recently become the gold standard for minimally invasive treatment of PD, and studies have suggested the role of CCH could expand to the treatment of other urologic conditions such as urethral stricture disease...

INTRODUCTION: The study of the human orgasm has shown a core set of physiologic and psychological symptoms experienced by most individuals. The study of normal sheds light on the abnormal and has spotlighted rare physical and psychological symptoms experienced by some individuals in association with orgasm. These phenomena are rare and, as is typical of rare phenomena, their documentation in the medical literature is largely confined to case studies. AIM: To identify peri-orgasmic phenomena, defined as unusual physical or psychological symptoms subjectively experienced by some individuals as part of the orgasm response, distinct from the usual or normal orgasm response...
