Chromosome Organization in Early Meiotic Prophase

open access: yesFrontiers in Cell and Developmental Biology, 2021
One of the most fascinating aspects of meiosis is the extensive reorganization of the genome at the prophase of the first meiotic division (prophase I). The first steps of this reorganization are observed with the establishment of an axis structure, that

The Mystery of Handprints: Assesment and Correlation of Dermatoglyphics with Early Childhood Caries A Case-Control Study [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2015
Background: It has been acknowledged that genetics play a significant role in determination of dermatoglyphic patterns. Since caries is a multifactorial disease with the influence of genetic pattern, this study was undertaken to assess dermatoglyphic

The Conformational Change of the L3 Loop Affects the Structural Changes in the Substrate Binding Pocket Entrance of β-Glucosidase

open access: yesMolecules, 2023
β-glucosidase (Bgl) hydrolyzes cellobiose to glucose, thereby releasing non-reducing terminal glucosyl residues. Bgl is an essential enzyme belonging to the biomass-degrading enzyme family, which plays a vital role in enzymatic saccharification during ...

BUCHSTEINER LOOPS

open access: yesInternational Journal of Algebra and Computation, 2009
Buchsteiner loops are those which satisfy the identity x \ (xy · z) = (y · zx) / x. We show that a Buchsteiner loop modulo its nucleus is an abelian group of exponent four, and construct an example where the factor achieves this exponent.

Oxytocinergic Feedback Circuitries: An Anatomical Basis for Neuromodulation of Social Behaviors

open access: yesFrontiers in Neural Circuits, 2021
Oxytocin (OT) is a neuropeptide produced by hypothalamic neurons and is known to modulate social behavior among other functions. Several experiments have shown that OT modulates neuronal activity in many brain areas, including sensory cortices.

Constructing Cycles in Isogeny Graphs of Supersingular Elliptic Curves

open access: yesJournal of Mathematical Cryptology, 2021
Loops and cycles play an important role in computing endomorphism rings of supersingular elliptic curves and related cryptosystems. For a supersingular elliptic curve E defined over 𝔽p2, if an imaginary quadratic order O can be embedded in End(E) and a ...
