Parameterization invariance and shape equations of elastic axisymmetric vesicles

open access: yes, 1994
The issue of different parameterizations of the axisymmetric vesicle shape addressed by Hu Jian-Guo and Ou-Yang Zhong-Can [ Phys.Rev. E {\bf 47} (1993) 461 ] is reassesed, especially as it transpires through the corresponding Euler - Lagrange equations ...

Exploring the differences between forward osmosis and reverse osmosis fouling [PDF]

open access: yes, 2018
A comparison of alginate fouling in forward osmosis (FO) with that in reverse osmosis (RO) was made. A key experimental finding, corroborated by membrane autopsies, was that FO is essentially more prone to fouling than RO, which is opposite to a common ...

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

A histological study of the black-winged kite's retina (Elanus caeruleus, Desfontaines, 1789)

open access: yesمجلة بغداد للعلوم
The study showed the retina of the diurnal invasive raptor Elanus caeruleus is avascular and supplied nutrition and oxygen by the choroid and pecten oculi. The retina includes two layers: the outer layer is called the pigmented epithelium, and the inner

Observations on the physiological development of trout eggs [Translation from: Roux. Arch. f. Entwicklungsmechanik der Organismen, 114. 771, 1929] [PDF]

open access: yes, 1929
The osmotic pressure of the perivitelline fluid and the yolk of trout (Salmo trutta) eggs were measured separately by the Drucker-Schrein method. The permeability of the egg membrane and the variations in the osmotic pressure of the eggs when placed in ...

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Characteristics of macular edema associated with retinal vein occlusion showing poor anatomic response to three loading anti-vascular endothelial growth factor injections: an optical coherence tomography analysis

open access: yesBMC Ophthalmology
Purpose To analyze the clinical features of refractory cystoid macular edema related to retinal vein occlusion associated with the response to three consecutive loading doses of anti–vascular endothelial growth factor.

Mucoepidermoid carcinoma of the conjunctiva with lung metastasis

open access: yesIndian Journal of Ophthalmology, 2015
A 36-year-old lady presented with redness and decreased vision in right eye since 6 months. She was earlier diagnosed of cavitary lung lesion, presumed secondary to tuberculosis and treated with anti-tubercular treatment for 4 months.

Anaerobic membrane bioreactors: Are membranes really necessary? [PDF]

open access: yes, 2008
Membranes themselves represent a significant cost for the full scale application of anaerobic membrane bioreactors (AnMBR). The possibility of operating an AnMBR with a self-forming dynamic membrane generated by the substances present in the reactor ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
