Prefrontal and parietal regions are involved in naming of objects seen from unusual viewpoints

Object naming is commonly used for demonstrating semantic memory abilities, known to be affected in normal aging. Yet, neuropsychological assessments of older people do not reflect irregularities. The authors used a test with 2 levels of naming complexity by 2 kinds of stimuli: common objects pictured from a conventional viewpoint (usual condition) or from an unconventional viewpoint (unusual condition). The authors studied naming performance with 129 healthy participants, aged 20-85 years. For the usual stimuli, the success rate was high (90.9%), with no reduction in performance until 65 years of age. However, for the unusual stimuli, there was a marked reduction in performance with age. Brain activity was studied on 11 healthy young participants (20-30 years of age) using functional magnetic resonance imaging. The usual condition activated brain regions associated with visual perception, language, and memory. Additional brain regions associated with semantic searching and decision making were obtained in the unusual condition in the prefrontal cortex (Brodmann's area [BA] 9 and BA 47) and anterior cingulate (BA 32). The results suggest that the poor naming performance for unusual-viewed objects in older people might be related to the shrinkage of frontal gray matter with age.     

Ethylene glycol intoxication: a case report

Ethylene glycol intoxication is one of the most serious acute poisonings due to the high toxicity that can result in death if not treated rapidly. We report the case of a patient who presented to the intensive care unit with a hypertensive crisis associated to a renal insufficiency. Laboratories investigations which revealed metabolic acidosis and elevated anion gap, highlighted an unexpected ethylene glycol intoxication. Clinical and psychiatric feature lead to suspect a chronic ingestion. Spontaneous recovery occured without specific treatment.     

Effect of training program regarding smoking cessation counseling for primary health care physicians in Port Said City,Egypt

Background

Smoking is a major risk factor for death-related diseases. Not all healthcare professionals are following evidence-based guidelines for smoking cessation counseling in primary care settings. The WHO, Framework Convention on Tobacco Control (FCTC), and United States Public Health Service (USPHS) guidelines recommend that all healthcare professionals, including students in healthcare training programs, receive education in the management of tobacco use and dependence.

Objective

To evaluate the effect of training programs for primary healthcare physicians on the knowledge, attitude, and practice of smoking cessation counseling.

Methods

This was a pre-post intervention study. The study included 74 primary care physicians working in primary healthcare centers affiliated with the Ministry of Health and Suez Canal University Hospitals in Port Said City. The study was conducted between June 2015 and March 2016 using a structured questionnaire and observation checklist to assess counseling of patients willing to quit smoking.

Results

There were highly statistically significant improvements in the physicians’ median scores of knowledge (30%–80%), attitude (65% -100%), and practice (20%–70%) (p?<?0.001) pre-post intervention. The most frequent correct knowledge was consequences of smoking (73%–87.3%) (p?<?0.001) pre-post intervention. The most favorable attitude was the importance of smoking cessation (70.3%–100%) (p?<?0.001) pre-post intervention. The best observed correct practice was asking about smoking (70.3%–100%) (p?<?0.001) pre-post intervention.

Conclusion

Knowledge, attitude, and practice skills regarding smoking cessation counseling among primary healthcare physicians were markedly improved after implementation of the education program.

     

Metal-free functionalized carbonized cotton for efficient solar steam generation and wastewater treatment

Water desalination via solar steam generation is one of the most important technologies to address the increasingly pressing global water scarcity. Materials for solar photothermal energy conversion are highly sought after for their cost savings, environmental friendliness and broad utility in many applications including domestic water heating and solar-driven desalination. Herein, we report the successful development of metal-free, low weight and cost effective functionalized carbonized cotton (CC) fibers for efficient solar water desalination and wastewater treatment. The CC fibers with nearly full solar spectrum absorption, efficient photo-thermal conversion and low-cost could provide excellent alternatives to the high-cost plasmonic-based materials for solar water desalination. We also report on a novel and simple device to mitigate the issues associated with conductive heat loss by utilizing the economically viable carbonized cotton materials as an irradiation surface placed on a low-density polyethylene foam that floats on the surface of seawater. The CC solar steam generation device exhibits average water evaporation rates of 0.9, 6.4 and 10.9 kg m⁻² h⁻¹ with impressive solar-to-vapor efficiencies of 59.2, 88.7 and 94.9% under 1, 5 and 8 sun illumination, respectively. Moreover, the device displays excellent durability showing stable evaporation rates over 10 steam generation cycles under 5 sun of solar intensity. Furthermore, the applicability of the CC device for the removal of organic dyes from contaminated water through solar steam generation is also demonstrated. The low-cost, simple design, high solar thermal evaporation efficiency, excellent stability and long-term durability make this CC device a perfect candidate for applications in seawater desalination and wastewater treatment by solar steam generation.

Inhibition of the TRPC5 ion channel protects the kidney filter

An intact kidney filter is vital to retention of essential proteins in the blood and removal of waste from the body. Damage to the filtration barrier results in albumin loss in the urine, a hallmark of cardiovascular disease and kidney failure. Here we found that the ion channel TRPC5 mediates filtration barrier injury. Using Trpc5-KO mice, a small-molecule inhibitor of TRPC5, Ca²⁺ imaging in isolated kidney glomeruli, and live imagining of podocyte actin dynamics, we determined that loss of TRPC5 or its inhibition abrogates podocyte cytoskeletal remodeling. Inhibition or loss of TRPC5 prevented activation of the small GTP-binding protein Rac1 and stabilized synaptopodin. Importantly, genetic deletion or pharmacologic inhibition of TRPC5 protected mice from albuminuria. These data reveal that the Ca²⁺-permeable channel TRPC5 is an important determinant of albuminuria and identify TRPC5 inhibition as a therapeutic strategy for the prevention or treatment of proteinuric kidney disease.
