Stephen T Trumbo

Curr Opin Insect Sci 2018 Aug 7;28:13-18. Epub 2018 Apr 7.

Department of Ecology and Evolutionary Biology, University of Connecticut, Waterbury, CT 06710, USA.

Juvenile hormone (JH) has both gonadotropic and non-gonadotropic roles in eusocial insects. There is controversy over whether the non-gonadotropic role is novel, related specifically to social evolution, or is a second conserved role. Study of subsocial insects suggests that when JH is non-gonadotropic, the specific associations of high JH, low vitellogenin, suppressed ovarian development and elevated metabolism may parallel those in workers of eusocial insects.

Biomolecules 2018 Dec 13;8(4). Epub 2018 Dec 13.

Department of Medical Laboratory Sciences, Jordan University of Science and Technology, Irbid 22110, Jordan.

Enhancing testosterone production in males is a continuous research direction for many scientists in the field, due to its role as a principal sex hormone and as a crucial modulator of well-being and general health in humans. Since 1978, there have been more than 30 studies that have connected coenzyme Q and testosterone. Such a link is attributable to the vigorous biological role of coenzyme Q as a crucial member in the energy production route in humans and animals, which is thought to have a positive influence on testosterone production, and hence on infertility, particularly male infertility.

[FSGS collapsing variant during anabolic steroid abuse: Case Report].

G Ital Nefrol 2018 Dec;35(6)

UO Nefrologia e Dialisi AUSL Romagna Ospedale Infermi Rimini.

Anabolic Androgenic Steroids (AAS) is an hormone family whose use has considerably increased among body-builders during the last decades. The AAS abuse, especially associated with other drugs or nutritional supplements and protein loads, may cause a variety of pathologies to several organs with a mechanism related to dosage, timing and substance. The kidney is the main metabolizer of these drugs and it can be acutely or chronically damaged with ESKD. Read More

ADH is a hormone secreted by neurohypophysis that plays different roles based on the target organ. At the renal level, this peptide is capable of causing electrolyte-free water absorption, thus playing a key role in the hydro-electrolytic balance. There are pathologies and disorders that jeopardize this balance and, in this field, ADH receptor inhibitors such as Vaptans could play a key role. Read More

Type I IFNs in the female reproductive tract: The first line of defense in an ever-changing battleground.

J Leukoc Biol 2018 Dec 14. Epub 2018 Dec 14.

Department of Medical Gerontology, Trinity Translational Medicine Institute, Trinity College Dublin, Dublin, Ireland.

The primary function of the female reproductive tract (FRT) is to enable successful reproduction, yet the biologic mechanisms required to accomplish this, which include fluctuating sex hormones and tolerance of semen and a semi-allogeneic fetus, can leave this unique mucosal environment susceptible to pathogenic challenge. Consequently, the FRT has evolved specialized innate and adaptive immune responses tailored to protecting itself from infection without compromising reproductive success. A family of innate immune cytokines that has emerged as important regulators of these immune responses is the type I IFNs. Read More

Dermapen in the treatment of wrinkles in cigarette smokers and skin aging effectively.

J Cosmet Dermatol 2018 Dec;17(6):1200-1204

Department of Dermatology & Venereology, Medical School, Zagazig University, Cairo, Egypt.

Skin aging is a complex biological process that arises from two basic processes: intrinsic aging (influenced by genetics factors, cellular metabolism, hormone, and metabolic processes) and extrinsic aging caused by chronic light exposure, pollution, ionizing radiation, chemicals, toxins (Expert Opin Biol Ther. 2008;8:393). Intrinsic aging called also chronological aging is observed in sun-protected skin of elderly persons. Read More

Voiding behavior and chronic pelvic pain in two types of rat nonbacterial prostatitis models: Attenuation of chronic pelvic pain by repeated administration of tadalafil.

Prostate 2018 Dec 14. Epub 2018 Dec 14.

Research Laboratories, Nippon Shinyaku Co., Ltd., Minami-ku, Kyoto, Japan.

Background: Experimental autoimmune prostatitis (EAP) and prostatitis induced by 17β-estradiol treatment combined with castration (hormone/castration-induced prostatitis; HCP) are the most commonly used rodent models of nonbacterial prostatitis. We studied the effect of the phosphodiesterase 5 inhibitor tadalafil on chronic pelvic pain in two such models in rats.

Methods: EAP was induced by intradermal injection of rat prostate antigen and complete Freund's adjuvant on Days 0 and 28. Read More

Mechanisms of Sex Disparities in Cardiovascular Function and Remodeling.

Compr Physiol 2018 Dec 13;9(1):375-411. Epub 2018 Dec 13.

Department of Physiology and Anatomy, University of North Texas Health Science Center, Fort Worth, Texas, USA.

Epidemiological studies demonstrate disparities between men and women in cardiovascular disease prevalence, clinical symptoms, treatments, and outcomes. Enrollment of women in clinical trials is lower than men, and experimental studies investigating molecular mechanisms and efficacy of certain therapeutics in cardiovascular disease have been primarily conducted in male animals. These practices bias data interpretation and limit the implication of research findings in female clinical populations. Read More

Regulation of Red Blood Cell Volume with Exercise Training.

Compr Physiol 2018 Dec 13;9(1):149-164. Epub 2018 Dec 13.

Center for Physical Activity Research, University Hospital Copenhagen, Denmark.

Hypervolemia is a hallmark of endurance training (ET) and manifests by similar elevations in plasma (PV) and red blood cell volume (RBCV) so that hematocrit largely remains unaltered following weeks/months of training. While the mechanisms facilitating PV expansion with ET have been previously reviewed extensively this is not the case for RBCV. Endurance champions may have 40% more RBCV than controls and RBCV may increase up to 10% following months of regular exercise training in healthy individuals. Read More

Comparative effectiveness of radiotherapy for early-stage hormone receptor-positive breast cancer in elderly women using real-world data.

Cancer Med 2018 Dec 12. Epub 2018 Dec 12.

Pharmaceutical Outcomes & Policy (POP), College of Pharmacy, University of Florida, Gainesville, Florida.

Background: Radiotherapy is the recommended treatment after breast-conserving surgery (BCS) for early-stage breast cancer (BC). However, there is no clear evidence whether radiotherapy after BCS improves the survival of elderly women diagnosed with early-stage hormone receptor-positive (HR+) BC. The aim of this study was to investigate the survival benefit associated with radiotherapy plus hormonal therapy vs hormonal therapy alone after BCS for early-stage HR+ BC patients. Read More
