Inside Post-Socialist Courts: The Determinants of Adjudicatory Outcomes in Slovenian Commercial Disputes

Despite the judiciary's central role in the capitalist market system, micro-level empirical analyses of courts in post-socialist countries are remarkably rare. This paper draws on a unique hand-collected dataset of commercial claims filed at Slovenian courts to examine the determinants of two salient adjudicatory outcomes: whether a case was resolved via trial or settlement and if the case was tried, whether the plaintiff was awarded the initial claim. Consistent with the divergent expectations theory of litigation, we find that trial-based resolution is more likely when the case is complex and less likely when parties use mediation. Addressing sample selection and endogeneity concerns, we show that defendant's legal representation, plaintiff's profitability, and, importantly, court identity are robust predictors of plaintiff victory at trial. Thus, more than two decades after the start of transition in Slovenia, the judicial system is still a source of legal inconsistency and uncertainty

Rapid Reuse of Readily Releasable Pool Vesicles at Hippocampal Synapses

AbstractFunctional presynaptic vesicles have been subdivided into readily releasable (RRP) and reserve (RP) pools. We studied recycling properties of RRP vesicles through differential retention of FM1-43 and FM2-10 and by varying the time window for FM dye uptake. Both approaches indicated that vesicles residing in the RRP underwent rapid endocytosis (τ ≅ 1 s), whereas newly recruited RP vesicles were recycled slowly (τ ≅ 30 s). With repeated challenges (hypertonic or electrical stimuli), the ability to release neurotransmitter recovered 10-fold more rapidly than restoration of FM2-10 destaining. Finding neurotransmission in the absence of destaining implied that rapidly endocytosed RRP vesicles were capable of reuse, a process distinct from repopulation from the RP. Reuse would greatly expand the functional capabilities of a limited number of vesicles in CNS terminals, particularly during intermittent bursts of activity

Ovotestis in Adolescence: 2 Case Reports

We present 2 patients found to have ovotesticular disorder of sexual development (otDSD) in late adolescence. Two 15-year-old phenotypically male patients presented to a large pediatric hospital with different complaints: 1 with concern for testicular rupture after a straddle injury; 1 with gynecomastia. Further workup, including imaging and laboratory tests, was performed before surgical exploration. The first patient had unilateral ovotestis, contralateral testis, and SRY-negative 46,XX karyotype. The second patient with gynecomastia had unilateral ovotestis with hemi-uterus and fallopian tube, contralateral ovarian tissue, and 46,XX/47,XXY Klinefelter mosaic karyotype. Although rare, phenotypically normal male patients may present later with ovotesticular disorder of sexual development
