A morphometric study of arch of the great saphenous vein and its clinical significance

Journal of Dr. NTR University of Health Sciences, 2016
Objective: Varicosities in the lower limbs are the most important afflictions of the venous system, as well as of the peripheral vascular disorders. They are always caused by a fault in the valves inside the veins at the point where the superficial veins

Gallbladder duplication

International Journal of Surgery Case Reports, 2015
Gallbladder duplication is a rare congenital malformation that occurs in about one in 4000 births. Congenital anomalies of the gallbladder and anatomical variations of their positions are associated with an increased risk of complications after laparoscopic cholecystectomy.We report the case of a double gallbladder in a fifty-six year old man.

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

FEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

Lines of corn L-70/9 and B-73 RfC are carrying the gene Rf4 on the same loci [PDF]

Selekcija i Semenarstvo, 2004
The inheritance of the fertility restoration in cms-C in maize is very complex, and there are many contradictory results in the literature. There is an indication that there are different parallel or duplicated systems some of which include at least ...

The numerical duplication of a numerical semigroup

, 2012
In this paper we present and study the numerical duplication of a numerical semigroup, a construction that, starting with a numerical semigroup $S$ and a semigroup ideal $E\subseteq S$, produces a new numerical semigroup, denoted by $S\Join^b\E$ (where ...

Combined 5‐aminolevulinic acid and ferric ammonium citrate treatment promotes hair follicle growth by activating dermal papilla cells

FEBS Open Bio, EarlyView.
5‐Aminolevulinic acid combined with ferric ammonium citrate (5‐ALA/FAC) stimulates dermal papilla cell activity and promotes hair follicle growth. The treatment enhances ERK and AKT signaling, increases hair‐inductive gene expression, and restores dermal papilla function suppressed by dihydrotestosterone and oxidative stress, resulting in enhanced hair

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

FEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Copy-number changes in evolution: rates, fitness effects and adaptive significance

Frontiers in Genetics, 2013
Gene copy-number differences due to gene duplications and deletions are rampant in natural populations and play a crucial role in the evolution of genome complexity.

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

FEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Duplication appendiculaire révélé à l'occasion d'un syndrome appendiculaire récidivant

The Pan African Medical Journal, 2015
La duplication appendiculaire est une malformation très rare. Elle se rencontre chez les enfants exceptionnellement chez les adultes. Sa découverte est souvent fortuite à l'occasion d'une laparotomie ou laparoscopie pour une autre pathologie.
