BRCA2 is a multifunctional tumor suppressor involved in homologous recombination (HR), mitotic checkpoint regulation, and telomere homeostasis. Absence of Brca2 in mice results in progressive shortening of telomeres and senescence, yet cells are prone to neoplastic transformation with elongated telomeres, suggesting that BRCA2 has positive and negative effects on telomere length regulation along the path to tumorigenesis. Using Caenorhabditis elegans as a model, we show here that depletion of BRC-2, an ortholog of BRCA2, paradoxically delays senescence in telomerase-deficient mutant worms...

Maternally derived antibodies (MDA) don not protect turkeys against rhinotracheitis (TRT) but high MDA influences upper respiratory tract (URT) immunity stimulation after avian Metapneumovirus (aMPV) vaccination. Humoral immunity can not be considered as an indicator of protection against TRT, but specific antibodies inhibit aMPV replication and alleviate the course of TRT. Scarce reports indicate the role of IgA in protection against TRT. The aim of our study was to investigate the impact of MDA on stimulation, antigen specificity acquisition of B lymphocytes, and the production of specific IgA after TRT vaccination of turkeys...

BACKGROUND: Prophylactic cranial irradiation (PCI) is indicated for limited disease (LD) in small cell lung cancer (SCLC) patients who achieve a complete or near-complete response; however, it is sometimes not administered because of possible adverse reactions or patient refusal. Here we assessed treatment outcomes among patients with SCLC who were not treated with PCI. METHODS: The medical records of 60 patients (45 men, 15 women; mean age, 68 years; age range, 51-82 years) with SCLC were retrospectively reviewed...

INTRODUCTION: Attitudes regarding the safety of testosterone replacement therapy (TRT) in hypogonadal men with prostate cancer (PCa) have changed over the past few years with the emergence of case studies suggesting a low risk of cancer progression and a better understanding of the interaction of different levels of androgen with prostate cellular metabolism. This new view has the potential to change clinical practice. METHODS: Active members of the Canadian Urological Association were surveyed about their opinions on the safety of TRT in men with low-risk PCa, as well as their current prescribing habits...

STUDY OBJECTIVES: Type 3 home sleep apnea tests may underestimate the apnea-hypopnea index (AHI) due to overestimation of total sleep time (TST). We aimed to evaluate the effect of manual editing of the total recording time (TRT) on the TST and AHI. METHODS: Thirty 15-channel in-home polysomnography studies (AHI 0 to 30 events/h) scored using American Academy of Sleep Medicine criteria were rescored by two blinded polysomnologists after data from electroencephalogram, electrooculogram, and electromyogram were masked...

We report a Danio rerio transposon named DrTRT, for D. rerio Transposon Related to Tc1 The complete sequence of the DrTRT transposon is 1,563 base pairs (bp) in length, and its transposase putatively encodes a 338-amino acid protein that harbors a DD37E motif in its catalytic domain. We present evidence based on searches of publicly available genomes that TRT elements commonly occur in vertebrates and protozoa. Phylogenetic and functional domain comparisons confirm that TRT constitutes a new subfamily within the Tc1 family...

Ovarian antral follicles in the ewe grow in an orderly succession, producing 3 to 4 waves per estrous cycle. In prolific sheep, some large antral follicles from the second-to-last wave of the estrous cycle are added to the ovulatory follicles emerging just before estrus to give a higher ovulation rate; it is feasible that regression of these follicles is prevented by an increase in serum concentrations of FSH or LH pulsatility at proestrus. Prolific sheep tend to have a shorter luteal phase than nonprolific ewes and there is a great deal of evidence that luteal progesterone (P4), in addition to regulating LH release, may govern the secretion of FSH heralding the emergence of follicular waves...

Exposure to manganese (Mn) represents an environmental risk factor for Parkinson's disease (PD). Recent evidence suggests that telomerase reverse transcriptase (TERT), the catalytic subunit of mammalian telomerase participates in non-telomeric functions and may play a role in cellular protection from oxidative stress and DNA damage. trt-1 is the catalytic subunit of telomerase in Caenorhabditis elegans (C. elegans). The present study investigated the relationship between trt-1 mutation and Mn-induced neurotoxicity...

Opioid-induced androgen deficiency (OPIAD) was initially recognized as a possible consequence of opioid use roughly four decades ago. Long-acting opioid use carries risks of addiction, tolerance, and systemic side effects including hypogonadotropic hypogonadism with consequent testosterone depletion leading to multiple central and peripheral effects. Hypogonadism is induced through direct inhibitory action of opioids on receptors within the hypothalamic-pituitary-gonadal (HPG) and hypothalamic-pituitary-adrenal (HPA) axes as well as testosterone production within the testes...

We compared thrombophilia and hypofibrinolysis in 6 men with Klinefelter syndrome (KS), without previously known familial thrombophilia, who had sustained deep venous thrombosis (DVT)-pulmonary emboli (PE) or mesenteric artery thrombosis on testosterone replacement therapy (TRT). After the diagnosis of KS, TRT had been started in the 6 men at ages 11, 12, 13, 13, 19, and 48 years. After starting TRT, DVT-PE or mesenteric artery thrombosis was developed in 6 months, 1, 11, 11, 12, and 49 years. Of the 6 men, 4 had high (>150%) factor VIII (177%, 192%, 263%, and 293%), 3 had high (>150%) factor XI (165%, 181%, and 193%), 1 was heterozygous for the factor V Leiden mutation, and 1 was heterozygous for the G20210A prothrombin gene mutation...

The strict and efficient transcription termination is required to prevent production of aberrant read-through transcripts that may cause transcriptional interference at neighboring genes. However, the exact regulatory mechanism remains poorly understood. Through a genetic screening of a LUCIFERASE (LUC) reporter system, we found that Arabidopsis nucleosome remodeler DECREASE IN DNA METHYLATION1 (DDM1) is a key component of this regulatory machinery and plays an important role in transcription termination, thus limiting transcriptional read-through (TRT)...

INTRODUCTION: Male hypogonadism is characterized by inadequate production of Testosterone (T) (hypoandrogenism) and deficiencies in spermatogenesis. The main treatment of male hypogonadism is T replacement therapy (TRT), but for some of the patients, alternative drugs may be more suitable. AREAS COVERED: The available literature of T and alternative treatments for male hypogonadism are discussed. EXPERT OPINION: Transdermal application of T gels are the most commonly used route of T administration...

BACKGROUND: Many patients with limited disease small cell lung cancer (LD SCLC) suffer from comorbidity. Not all patients with comorbidity are offered standard treatment, though there is little evidence for such a policy. The aim of this study was to investigate whether patients with comorbidity had inferior outcomes in a LD SCLC cohort. MATERIAL AND METHODS: We analyzed patients from a randomized study comparing two three-week schedules of thoracic radiotherapy (TRT) plus standard chemotherapy in LD SCLC...

The knowledge of hydraulic properties of aquifers is important in many engineering applications. Careful design of ground-coupled heat exchangers requires that the hydraulic characteristics and thermal properties of the aquifer must be well understood. Knowledge of groundwater flow rate and aquifer thermal properties is the basis for proper design of such plants. Different methods have been developed in order to estimate hydraulic conductivity by evaluating the transport of various tracers (chemical, heat etc...

Despite a lack of evidence, there have been stated concerns that testosterone replacement therapy (TRT) can pose a risk to men suffering with lower urinary tract symptoms (LUTS)/benign prostatic hyperplasia (BPH). TRT may improve components of the metabolic syndrome, which is associated with worsening LUTS. Furthermore, the evidence suggests that TRT may decrease prostatic inflammation, which is also associated with worsening LUTS. The data on the relationship between TRT and LUTS have never shown worsening of LUTS, often show no change in LUTS, and occasionally show improvement...
