Plasmodium falciparum with pfhrp2 and pfhrp3 gene deletions in asymptomatic malaria infections in the Lake Victoria region, Kenya.

Malaria rapid diagnostic tests (RDTs) targeting the Plasmodium falciparum histidine-rich protein 2 (PfHRP2) are widely used to diagnose P. falciparum infection. However, reports of P.

CRISPR screens unveil nutrient-dependent lysosomal and mitochondrial nodes impacting intestinal tissue-resident memory CD8 T cell formation.

Nutrient availability and organelle biology direct tissue homeostasis and cell fate, but how these processes orchestrate tissue immunity remains poorly defined. Here, using in vivo CRISPR-Cas9 screens, we uncovered organelle signaling and metabolic processes shaping CD8 tissue-resident memory T (T) cell development. T cells depended on mitochondrial translation and respiration.

Outcome of Endoscopic Myringoplasty Using Gelfoam Versus no Gelfoam in Tympanic Cavity and External Auditory Canal.

Background Absorbable gelatin sponge (gelfoam) is used routinely during myringoplasty as a scaffold that supports tympanic membrane grafts and ossicular chain and to promote hemostasis. However, gelfoam could cause fibrosis, adhesions, granulations, new bone formation within the middle ear cavity and could obstruct the tympanic ostium of the eustachian tube and affects inner ear function and also interferes with the healing process of neodrum and middle ear cavity. Objective To compare the outcome of endoscopic myringoplasty with and without use of gelfoam in external auditory canal and tympanic cavity.
