Male seminal fluid allocation according to socio-sexual context in the South American fruit fly.

During copulation male insects transfer sperm and seminal fluids, including accessory gland proteins (Acps) to females, produced in the accessory glands (AGs). These Acps influence female behavior and physiology, inhibiting sexual receptivity, promoting ovulation and/or oviposition. The theory of ejaculate allocation postulates that production is costly; therefore, males strategically allocate ejaculates based on perception of sperm competition and quality and availability of females.

[Bartholinitis due to Neisseria meningitidis: Clinical case].

Bartholinitis is the inflammation and infection of the Bartholin's glands that results from the accumulation of mucus in their ducts, the most frequent causal microorganisms being anaerobic and aerobic bacteria and those responsible for sexually transmitted infections. Those caused by agents not belonging to the genital microbiota are less frequent. Likewise, in most cases the diagnosis is clinical.

Health outcomes reported by healthcare providers and clients of a community-based medically tailored meal program.

Background: Medically tailored meal (MTM) programs provide home-delivered meals to people living with serious illness and poor nutritional status. Client outcome studies have found evidence of decreased healthcare utilization and cost savings associated with MTM program participation, and inconclusive evidence of change in health measures. The purpose of this study was to use a novel observational framework to describe the client profile and change in health outcomes using routinely collected health and program data from a community-based MTM program at MANNA (Philadelphia, PA).

Effect of hydraulic retention time and treated urban wastewater ratio on progressive adaptation of an inoculated microalgae in membrane photobioreactors.

Currently, there is a growing concern about water scarcity. The rising demand for wastewater treatment systems that facilitate the reuse of wastewater has resulted in a focus on the use of microalgae in sustainable treatments. These methods not only eliminate nutrients from the wastewater but also produce biomass that can be used to obtain high-value products.

Hemorrhagic Cholecystitis Due to Rupture of Underlying Anomalous Duplicated Cystic Arteries.

Hemorrhagic cholecystitis (HC) is a rare complication that can become rapidly fatal. Patients may present with hematemesis or melena, in addition to other common symptoms of acute cholecystitis. Delay in diagnosing HC postpones early intervention, and patients can quickly decompensate.
