Lower Limb Edema Caused by Metastatic Signet Ring Cell Stomach Cancer.

Unlabelled: Overall gastric cancer incidence is decreasing, but incidence of gastric signet ring cell carcinoma has been rising. The diagnosis can be challenging. It has a poorer prognosis because it tends to be diagnosed at advanced stages.

Impacts of the COVID-19 pandemic and unpaid care work on informal workers' livelihoods.

The COVID-19 pandemic triggered a health, economic and care crisis affecting all workers, including those in the informal economy. This article uses data from the first round of a mixed-methods longitudinal study conducted in June/July 2020 by Women in Informal Employment: Globalizing and Organizing in partnership with informal workers' organizations in 12 cities. It assesses the impacts of the multidimensional crisis on care responsibilities and the resulting effects on livelihoods and food security.

Disseminated Nocardiosis: The Complexity of the Diagnosis.

Nocardiosis is a rare infection in immunocompetent patients. is an uncommon cause of prostate abscesses and is responsible for only 1-2% of brain abscess. Hematogenous dissemination can occur, and presentation of abscesses in more than two locations is required to determine a disseminated nocardiosis.

Different doses of estradiol benzoate induce conditioned place preference after paced mating.

The ovarian hormones estrogen and progesterone are required for the complete display of sexual behavior in female rats. Paced mating produces a reward state in intact cycling and ovariectomized (OVX), hormonally primed females as evaluated by the conditioned place preference (CPP) paradigm. Most of the studies that have evaluated CPP induced by paced mating in OVX females have used relatively high doses of estradiol benzoate (EB).

Purification and characterization of an alpha-bungarotoxin receptor that forms a functional nicotinic channel.

Neither the structure nor the function of alpha-bungarotoxin (alpha Bgtx) binding molecules in the nervous system have yet been completely defined, although it is known that some of these molecules are related to cation channels and some are not. Using an improved method of affinity chromatography, we have isolated a toxin binding molecule from chicken optic lobe that contains at least three subunits with apparent Mr values of 52,000, 57,000, and 67,000. The Mr 57,000 subunit binds alpha Bgtx and seems to be present in two copies per receptor.
