Background: Urban malaria has received insufficient attention in the literature. The prevalence and clinical characteristics of Plasmodium falciparum infection amongst patients presenting with suspected malaria were investigated at a major urban hospital in Douala, Cameroon with a particular focus on anaemia.
Methods: A cross-sectional, 18-week demographic and clinical survey was conducted of patients presenting to the Emergency Department of Douala Military Hospital with suspected malaria, largely defined by the presence or recent history of fever.

Muscle function and mass begin declining in adults long before evidence of sarcopenia and include reduced mitochondrial function, although much remains to be characterized. We found that mRNA decay factor AU-rich mRNA binding factor 1 (AUF1), which stimulates myogenesis, is strongly reduced in skeletal muscle of adult and older mice in the absence of evidence of sarcopenia. Muscle-specific adeno-associated virus (AAV)8-AUF1 gene therapy increased expression of AUF1, muscle function, and mass.

Much of current NCDs are generally due to genetic, behavioral, and metabolic risk factors that often include excessive alcohol consumption, smoking, obesity, and untreated elevated blood pressure, and share many common signal transduction pathways. Alterations in cell and physiological signaling and transcriptional control pathways have been well studied in several human NCDs, but these same pathways also regulate expression and function of the protein synthetic machinery and mRNA translation which have been less well investigated.

AUF1 depletion in mice accelerates muscle loss and causes limb girdle muscular dystrophy. Here, we demonstrate that the selective, targeted degradation by AUF1 of key muscle stem cell fate-determining checkpoint mRNAs regulates each stage of muscle development and regeneration by reprogramming each myogenic stage.

Hair follicle mites were recovered and identified as Demodex kutzeri, a species originally described from the European red deer (Cervus elaphus, from Austria) and the sika deer (Cervus nippon pseudaxis, captive in Germany). These findings expand the geographic range of D.

Clinical evaluation revealed a strong left-sided heart murmur and a split S2 sound. The calf died within 48 hours.

All 16 had gliosis throughout all sections of the brain. Most had lymphoplasmacytic encephalitis or meningoencephalitis, many with admixed neutrophils.
