In line with this observation, we find that TRα is widely expressed in the tanycytes. Altogether, our data demonstrate that the melatonin-driven T3 signal regulates RFRP-3 neurons through non-neuronal, possibly tanycytic, TRα.

What is the central question of this study? Does the administration of the adrenergic presynaptic release inhibitor bretylium tosylate modulate sweating during exercise in the heat, and does this response differ between habitually trained and untrained men? What is the main finding and its importance? Iontophoretic administration of bretylium tosylate attenuates sweating during exercise in the heat in habitually trained and untrained men. However, a greater reduction occurred in trained men. The findings demonstrate a role for cutaneous adrenergic nerves in the regulation of eccrine sweating during exercise in the heat and highlight a need to advance our understanding of neural control of human eccrine sweat gland activity.

We recently reported an influence of cutaneous adrenergic nerves on eccrine sweat production in habitually trained men performing an incremental exercise bout in non-heat stress conditions. Based on an assumption that increasing heat stress induces cholinergic modulation of sweating, wrained men. While it is accepted that a cholinergic mechanism plays a primary role in the regulation of sweating during an exercise-heat stress, our findings highlight the need for additional studies aimed at understanding the neural control of human eccrine sweating.Propolis, a resinous substance, is collected from plants and processed by honeybees to seal holes and cracks in beehives, protecting them from microbial infection. Based on the plant source and geographical location, propolis is categorized into seven groups. Of these, Pacific propolis, found in the Pacific islands, originates from Macaranga spp. and is, therefore, known as Macaranga-type Pacific propolis. Okinawa propolis and Taiwanese propolis, which are both Macaranga-type propolis, are rich in prenylated flavonoids from the same botanical source, Macaranga tanarius, and are used locally as traditional remedies. They are reported to have a wide range of pharmacological benefits, including antioxidant, anti-inflammation, antimicrobial, anticancer, antidiabetic, anti-Alzheimer's, anti-melanogenic, and longevity-extending effects. However, not much is known about their mode of action, and recently, the extract of Okinawa propolis and its major prenylated flavonoids were found to selectively inhibit the oncogenic kinase, p21-activated kinase 1 (PAK1). PAK1 enables cross-talking among several signaling pathways, causing many diseases/disorders. The existing results reviewed here support the use of Macaranga-type Pacific propolis for the effective development of safe herbal drugs and functional foods. Furthermore, its mode of action by modulating PAK1 can be explored, and the geographical and seasonal effects on its chemistry and biology, and its pharmacokinetics and toxicology should be studied as well.Chalcogen bonds are σ hole interactions and have been used in recent years as an alternative to hydrogen bonds. In general, the electrostatic potential at the chalcogen atom and orbital delocalization effects are made responsible for the orientation of the chalcogen bond. Here, we were able to show by means of SAPT calculations that neither the induction (orbital delocalization effects) nor the electrostatic term is causing the spatial orientation of strong chalcogen bonds in tellurium-containing aromatics. Instead, steric interactions (Pauli repulsion) are responsible for the orientation. Against chemical intuition the dispersion energies of the examined tellurium-containing aromatics are far less important for the net attractive forces compared to the energies in the corresponding sulfur and selenium compounds. Our results underline the importance of often overlooked steric interactions (Pauli repulsion) in conformational control of σ hole interactions.

Our aim was to evaluate the feasibility and safety of laparoscopic sacrocolpopexy (LSCP) and compare the long-term outcomes and complication rates of polypropelene (PP) and polyvinylidene fluoride (PVDF), following up within a minimum of 12 months.

This was a retrospective cohort study using patients who underwent LSCP for POP involving either PP or PVDF mesh between January 2011 and January 2018.

Our study focused on 172 women who underwent LSCP with mesh between January 2011 and January 2018. All procedures were successfully completed laparoscopically, and patients' baseline characteristics were not statistically different in the two groups. Between January 2011 and December 2014, we performed 82 cases of LSC, mainly using PP mesh. Over the last 5 years, since January 2015, we have used PVDF mesh for POP.

LSCP using PVDF mesh was found to provide excellent anatomical and functional outcomes after a median follow-up duration of 41 months, compared with the PP group, which had a median follow-up duration of 54 months. Mesh infection and erosion rates in the PP group were significantly higher than those in the PVDF group. Additionally, rates of vaginal pain and discomfort were significantly lower in the PVDF group when compared with the PP group.

Adversary effects refer to the tendency of offenders to make tactical decisions based on the coercive power of victims and potential victims. Using the victim's gender as a proxy for coercive power, we analyzed violent incidents from the National Incident-Based Reporting System (2005-2014). The sample included over six million assaults, robberies, and homicides. Consistent with adversary effects, offenders who attack males (vs. females) are more likely to (a) kill victims; (b) use guns, knives, blunt objects, poison, and automobiles; (c) use male (but not female) allies; and (d) use multiple allies. The evidence for target choice is mixed unarmed female offenders, but not unarmed male offenders, are more likely to target females than males. The evidence shows how a simple theoretical principle can parsimoniously account for basic patterns of violence in society related to gender, weapons, and group violence.
