[Roux-Y reconstruction following distal stomach resection using only staplers].

The spreading of stapled suture techniques has also entailed the utilization of staplers in gastric surgery. A functional, up-to-date, and exclusively stapled reconstruction procedure, Roux-Y-reconstruction, after subtotal gastrectomy was established and analyzed in a pilot study (n = 25). In doing so, one proceeded as follows after subtotal gastrectomy and systematic lymphadenectomy in cases of carcinoma: duodenal closure (GIA or TA30), gastric resection (TA90), jejunojejunostomy (EEA25), gastrojejunostomy (EEA25/28), closure of the projecting efferent loop (GIA).

Floccular efferents in the rhesus macaque as revealed by autoradiography and horseradish peroxidase.

To fulfill its putative role in short- and long-term modification of the vestibulo-ocular reflex, the flocculus of the cerebellum must send efferents to brainstem nuclei involved in the control of eye movements. In order to reveal the sites of these interactions, we determined the projections of the flocculus by autoradiography and orthograde transport of horseradish peroxidase in five rhesus macaques. Anterogradely labeled axons collected at the base of the injected folia and coursed caudally and medially between the middle cerebellar peduncle and the flocculus.

Afferents to the flocculus of the cerebellum in the rhesus macaque as revealed by retrograde transport of horseradish peroxidase.

To investigate the afferent projections to the flocculus in a nonhuman primate, we injected horseradish peroxidase into one flocculus of six rhesus macaques (Macaca mulatta) and processed their brains according to the tetramethylbenzidine protocol to reveal retrogradely labeled neurons. Labeled neurons were found in a large set of nuclei within the rostral medulla and the pons. The greatest numbers of labeled neurons were in the vestibular complex and the nucleus prepositus hypoglossi.

Complete sequence of a gene encoding a human type I keratin: sequences homologous to enhancer elements in the regulatory region of the gene.

We report here the complete nucleotide sequence of a gene encoding the 50-kDa keratin expressed in abundance in human epidermal cells. According to its sequence, this gene has a single transcriptional initiation site and a single polyadenylylation signal. Nuclease S1 mapping of this gene with total human epidermal mRNA confirmed the presence of a single initiation site for the 50-kDa keratin gene.

Sex-dependent induction of human suppressor T cells by chorionic gonadotropin.

Human chorionic gonadotropin (hCG) in physiological retroplacental concentration has been shown to induce human female lymphocytes which suppress the proliferation and differentiation of B cells stimulated by purified protein derivative of tuberculin. To test whether the hCG-induced suppression was sex dependent parallel experiments using female and male peripheral lymphocytes were performed. hCG did not induce cells capable of suppressing purified protein derivative induced B cell proliferation in lymphocytes from males, which was in contrast to lymphocytes from females where a statistically significant suppression was found.

Spatial and temporal properties of X and Y cells in the cat lateral geniculate nucleus.

1. Extracellular recordings were obtained from units in the dorsal lateral geniculate nucleus of anaesthetized cats. 2.

Comparative calcium ion determinations in plasma and whole blood with a new calcium ion analyzer.

A new Ca2+ analyzer has been used for the determination of Ca2+ in plasma and whole blood from normal subjects and patients with disorders of calcium metabolism. The results were nearly identical: the equation of the regression line was y=1.02x-0.

Comparison of three intrauterine contraceptive devices: the Antigon-F, the Ypsilon-Y, and the Copper-T 200.

A comparative study of three intrauterine contraceptive devices, the Antigon-F, the Copper-T, and the Ypsilon-Y, was carried out at The New York Hospital Cornell Medical Center during an 18-month period from March 1, 1972, through August 31, 1973. At the cutoff date of February 28, 1974, all patients had been followed for at least 6 months. During the period of study, 884 Antigon-F devices, representing 14,436 woman-months of use, were inserted.

Antibodies to yeast phenylalanine transfer ribonucleic acid are specific for the odd nucleoside ) in the anticodon loop.

Antibodies with specificity to a single species of tRNA were elicited in a goat by immunization with a glutaraldehyde conjugate of yeast phenylalanine transfer RNA with bovine gamma globulin. The specificity of the antibodies was studied by a radioimmunoassay measuring the direct binding of [(3)H]tRNA(Phe) or the inhibition of the binding. The antibodies formed are predominantly directed towards the characteristic highly modified nucleoside Y, which is located right next to the anticodon.
