We define two such pairs (X, i), (Y, j) to be equivalent if there is an isogeny α : X → Y such that if α̃ : End(X) ' End(Y ) is the induced isomorphism, we have α̃ ◦ i = j. It is easy to check that this is an equivalence relation. We write X ∼ Y if (X, i) is equivalent to (Y, j). Let AF be the collection of equivalence classes. We will classify such equivalence classes. Let D be any R-algebra. A ...

Thirty-six percent of American Wagyu bulls do not meet the current minimum standards set by the Society of Theriogenology for the breeding soundness exam. In contrast, only 15% of bulls of domestic breeds do not meet the minimum standards. Scrotal circumference measurements of Wagyu are smaller than those of other breeds. The objective of this research was to describe scrotal circumference of W...

A 24‐hour‐old, term neonate, weighing 3.4 kg, born by cesarean section presented with a huge sacral mass of size 20 cm × 20 cm, involving coccyx, extending to both buttocks, with intact skin [Figure 1]. Tumor resection was planned at 24 h of birth. Preoperative hemoglobin was 16 g/dl, and other investigations were within normal limits. Blood for grouping and crossmatching was sent. Chest roentg...

UNLABELLED OBJECTIVE, DESIGN AND SETTINGS: The purpose of this randomized, prospective study is to compare the efficacy of two different routes in administering epidural steroid injections interlaminar (IL) vs transforaminal (TF) in patients with unilateral radicular pain. PATIENTS We randomly enrolled and followed 64 patients with chronic radiculopathy. RESULTS Significant improvements wer...

BACKGROUND The evaluation of tools to accurately identify low birth weight (LBW) and/or premature newborns in resource-limited countries is a research priority. We explored the use of foot length, chest circumference, and mid-upper arm circumference (MUAC) measured within 24 h as diagnostic tools for identifying newborns who are LBW, premature, or both; and compared measurements taken at birth ...

The principal ion in the ionosphere of Triton is N+. Energetic electrons of magnetospheric origin are the primary source of ionization, with a smaller contribution due to photoionization. To explain the topside plasma scale height, we postulate that N+ ions escape from Triton. The loss rate is 3.4 x 10(7) cm-2 s-1 or 7.9 x 10(24) ions s-1. Dissociative recombination of N2+ produces neutral ...

BACKGROUND We assessed the potential of risk stratification of ARDS patients using SpO2/FiO2 and positive end-expiratory pressure (PEEP) at ARDS onset and after 24 h. METHODS We used data from a prospective observational study in patients admitted to a mixed medical-surgical intensive care unit of a university hospital in the Netherlands. Risk stratification was by cutoffs for SpO2/FiO2 and P...

In an unselected group of 37 patients with Parkinsonism the mean diameter of the oesophagus at the level of the 9th dorsal vertebra was 3·11 cm, which was significantly higher than the mean of 2·24 cm in a group of control patients. Six of the patients with Parkinsonism had gross oesophageal dilatation.

Bilateral adnexal torsion is a rare event in children. A high index of suspicion, together with prompt surgical treatment, would help to save the ovaries and preserve its function. We report a case of entangled bilateral adnexal torsion managed successfully via laparoscopy. An 11-year-old premenarchal girl complained of chronic intermittent abdominal pain that worsened over 24 hours. Computed t...
