Bioprospecting snakehead fish protein concentrate (SFC) as a non non-serumserum-based albumin source for promoting capacitation in bovine sperm

Journal of the Indonesian Tropical Animal Agriculture
Capacitation is a prerequisite for successful fertilization with albumin as an inevitable component among the oviductal fluid's constituents. Under in vitroenvironments, albumin's function is replaced by serum-based products, which carry the issue of ...

The Questioning of Special Items During Conference Calls: High Quality or Highly Questionable? Réexaminer des éléments exceptionnels lors des conférences téléphoniques : une pratique d'excellence ou très contestable?

Contemporary Accounting Research, EarlyView.
ABSTRACT Accounting standards require firms to distinguish recurring revenues and expenses from nonrecurring gains and losses, which are often referred to as special items. However, not all special items are genuinely nonrecurring. Exploiting the setting of earnings conference calls, we explore whether analysts can identify opportunistic special items,

Bottom-up approach to deciphering the targets of the ubiquitin-proteasome system in porcine sperm capacitation

Scientific Reports
Capacitation is an essential post-testicular maturation event endowing spermatozoa with fertilizing capacity within the female reproductive tract, significant for fertility, reproductive health, and contraception.

Fluorescent analysis of boar sperm capacitation process in vitro

Reproductive Biology and Endocrinology, 2019
Background Capacitation involves physiological changes that spermatozoa must undergo in the female reproductive tract or in vitro to obtain the ability to bind, penetrate and fertilize the egg.

Staffing Leverage at the Audit Office and Audit Quality L'influence de la dotation en personnel des bureaux d'audit sur la qualité des audits

Contemporary Accounting Research, EarlyView.
ABSTRACT The PCAOB posits that audit partner and manager involvement, primarily through greater supervision and review (“oversight”) of audit engagements, is an important determinant and indicator of audit quality. We test this notion by empirically examining the link between staffing leverage, as measured by an office's ratio of audit partners and ...

Forecasting ecological trajectories from ecological dynamic regimes to improve resilience analysis

Methods in Ecology and Evolution, EarlyView.
Abstract The ecological dynamic regime (EDR) framework was recently proposed as an alternative to equilibrium‐based approaches for assessing ecological resilience in empirical systems, explicitly incorporating dynamic regimes as a reference for assessing the system's deviation during disturbances.

Molecular mechanisms of mammalian sperm capacitation, and its regulation by sodium‐dependent secondary active transporters

Reproductive Medicine and Biology
Background Mammalian spermatozoa have to be “capacitated” to be fertilization‐competent. Capacitation is a collective term for the physiological and biochemical changes in spermatozoa that occur within the female body.

Toward a Politics of (In)Fertility: Reproductive Debility in Africa

American Anthropologist, EarlyView.
ABSTRACT Sub‐Saharan Africa has some of the highest estimated rates of infertility or involuntary childlessness in the world, leading epidemiologists to refer to parts of the region as the “infertility belt.” The medicalization of infertility and the situating of assisted reproductive technologies (ARTs) as the treatment for infertility have siphoned ...

CRISPR/Cas9‐mediated Genome‐editing Reveals 10 Testis‐enriched Genes and One Non‐testis‐enriched Gene are Dispensable for Male Fecundity in Mice

Andrology, EarlyView.
ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.

Expression of cystatin C in the female reproductive tract and its effect on human sperm capacitation

Reproductive Biology and Endocrinology, 2018
Background Cystatin C (CST3), a cysteine protease inhibitor in seminal plasma, is expressed in animal uteri. However, its expression in the human female reproductive tract and its effect on human sperm capacitation are unclear.
