The capacity of the infant to bear affect relies on the capacity of the caregiver until it has achieved enough strength to perform this task itself. In the case of neglect the necessary strength to contain, metabolize and think about affect so that it may be converted into differentiated feelings cannot develop because of the absence of a caregiver capable of sustaining the infant in its emotional development. Instead a system of defence against affect arises in which the affect itself is perceived as intrusive and abusive. Because of neglect a confusion between abuse and affect is to be observed, with catastrophic consequences for the growing up child. Furthermore neglected children can be seduced by external abuse in the hope of being protected from affect that threatens to feel abusive from within. Paradoxically these children are drawn toward abusive situations in the hope of finding some ongoing shelter from unmanageable affect. A corollary of this is that actual containment comes to feel abusive to them: if they are made to feel affect, they perceive the other, who put them in touch with affect, as abusive: thus affect, abuse and containment are confused. Clinical material will support this thesis.

Background: This study aimed to examine how physician performance metrics are affected by the speed of other attendings (co-attendings) concurrently staffing the ED.
Methods: A retrospective study was conducted using patient data from two EDs between January-2018 and February-2020. Machine learning was used to predict patient length of stay (LOS) conditional on being assigned a physician of average speed, using patient- and departmental-level variables.

Chronic pain is a pervasive and debilitating condition with increasing implications for public health, affecting millions of individuals worldwide. Despite its high prevalence, the underlying neural mechanisms and pathophysiology remain only partly understood. Since its introduction 35 years ago, brain diffusion magnetic resonance imaging (MRI) has emerged as a powerful tool to investigate changes in white matter microstructure and connectivity associated with chronic pain.

In species with genetic sex determination (GSD), the sex identity of the soma determines germ cell fate. For example, in mice, XY germ cells that enter an ovary differentiate as oogonia, whereas XX germ cells that enter a testis initiate differentiation as spermatogonia. However, numerous species lack a GSD system and instead display temperature-dependent sex determination (TSD).

Malignant gliomas are heterogeneous tumors, mostly incurable, arising in the central nervous system (CNS) driven by genetic, epigenetic, and metabolic aberrations. Mutations in isocitrate dehydrogenase (IDH1/2) enzymes are predominantly found in low-grade gliomas and secondary high-grade gliomas, with IDH1 mutations being more prevalent. Mutant-IDH1/2 confers a gain-of-function activity that favors the conversion of a-ketoglutarate (α-KG) to the oncometabolite 2-hydroxyglutarate (2-HG), resulting in an aberrant hypermethylation phenotype.

Precipitation recycling, where evapotranspiration (ET) from the land surface contributes to precipitation within the same region, is a critical component of the water cycle. This process is especially important for the US Corn Belt, where extensive cropland expansions and irrigation activities have significantly transformed the landscape and affected the regional climate. Previous studies investigating precipitation recycling typically relied on analytical models with simplifying assumptions, overlooking the complex interactions between groundwater hydrology and agricultural management.
