Supporting a rapid primary care response to emergent communicable disease threats with PACK (Practical Approach to Care Kit) in Florianópolis, Brazil.

Emerging infectious diseases present a significant challenge to healthcare systems with their need for a rapid response and reallocation of resources. This paper explores the implementation of the Practical Approach to Care Kit (PACK) programme in Florianópolis, Brazil as a strategic tool for reinforcing primary healthcare (PHC) responses to emergent communicable diseases. With its focus on enhancing PHC delivery in resource-limited settings, PACK provides a flexible, evidence-based framework that integrates into local health systems.

Carcass, meat quality traits, and economic analysis of Nellore bulls fed with finishing feedlot diets containing mechanically processed corn silage.

Effects of mechanical processing (MP) of corn silage and its inclusion in feedlot diets on carcass and meat quality traits of Nellore (Bos indicus) were analyzed. Seventy-two bulls aged approximately 18 months and with an initial average body weight of 392.8 ± 22.

COVID-19 cross-sectional study in Maricá, Brazil: The impact of vaccination coverage on viral incidence.

Population surveillance in COVID-19 Pandemic is crucial to follow up the pace of disease and its related immunological status. Here we present a cross-sectional study done in Maricá, a seaside town close to the city of Rio de Janeiro, Brazil. Three rounds of study sampling, enrolling a total of 1134 subjects, were performed during May to August 2021.

Photoprotective and antioxidant effects of Rhubarb: inhibitory action on tyrosinase and tyrosine kinase activities and TNF-α, IL-1α and α-MSH production in human melanocytes.

Background: Exposure to ultraviolet (UV) radiation causes various forms of acute and chronic skin damage, including immunosuppression, inflammation, premature aging and photodamage. Furthermore, it induces the generation of reactive oxygen species, produces proinflammatory cytokines and melanocyte-stimulating hormone (MSH) and increases tyrosinase activity. The aim of this study was to evaluate the potential photoprotective effects of Rheum rhaponticum L.

Correlation of β-catenin expresssion and metastasis in tongue squamous cell carcinoma.

Purpose: It has been reported that the oral squamous cell carcinoma (OSCC) in tongue shows a more infiltrative profile, aggressive clinical course and poor prognosis, which may be related to a higher metastatic potencial. The aim of the present study was to assess the expression of β-catenin in OSCC of the tongue and its correlation with tumor metastasis.

Methods: Twenty four cases were selected and divided in two groups: metastatic group (n=12) and non-metastatic group (n=12).

Transmittance photoplethysmography with near-infrared laser diodes in intra-peritoneal organs.

Photoplethysmography and pulse oximetry are techniques based on optical principles, which are widely used in medical practice for non-invasive monitoring. There are some processes which may affect specific organs or parts without a significant repercussion on the information provided non-invasively. Here, we report on the preliminary results obtained by transmittance photoplethysmography in pig intra-peritoneal organs along a surgical intervention, using a measurement system based on two near-infrared laser diodes.

Large disparity between gallium and antimony self-diffusion in gallium antimonide.

The most fundamental mass transport process in solids is self-diffusion. The motion of host-lattice ('self-') atoms in solids is mediated by point defects such as vacancies or interstitial atoms, whose formation and migration enthalpies determine the kinetics of this thermally activated process. Self-diffusion studies also contribute to the understanding of the diffusion of impurities, and a quantitative understanding of self- and foreign-atom diffusion in semiconductors is central to the development of advanced electronic devices.

Polymorphonuclear phagocytosis and killing in workers occupationally exposed to hexachlorobenzene.

Phagocytosis and intracellular killing of Candida albicans and Candida pseudotropicalis by neutrophils from 66 workers exposed to chlorinated compounds were studied. Phagocytosis with both antigens was normal in all the workers studied. However, lytic activity of the neutrophils in the presence of both antigens, C.

[Selective splenorenal shunt and post-transfusional hepatitis. Short and medium-term follow-up].

Eighteen patients with protal hypertension were studied. Portal hypertension was due to schistosomiasis (N = 9), cirrhosis (N = 7) and congenital hepatic fibrosis (N = 2) diagnosed by surgical biopsy during the decompressive surgery (selective splenorenal shunt). All the patients have had at least one episode of digestive hemorrhage due to rupture of esophageal varices and received blood transfusion before or during surgery.
