Preferential salivary-type hypoamylasemia in obese children.
Mizuuchi H,Taketa K
Acta Medica Okayama , 1999,
Abstract: Serum levels of total amylase, pancreatic type (P-type) isoamylase, and salivary type (S-type) isoamylase were measured in obese children (153 subjects; mean age, 10.1 years old; 86 boys and 67 girls) before and after weight reduction therapy. Serum amylase activities were determined using p-nitrophenylmaltoheptaoside as a substrate, with or without an antibody added to inhibit the S-type isoamylase. Serum levels of total amylase, P-type isoamylase and S-type isoamylase activities were significantly decreased in obese children with an obesity index more than 50%. S-type and P-type isoamylases showed negative correlation with the obesity index, the correlation coefficient being slightly larger in S-type than in P-type isoamylase. Analysis of the serum amylase activities in obese children who underwent weight reduction treatments showed a negative correlation only between the differences in S-type isoamylase activity and the differences in the obesity index. It may be concluded that the S-type isoamylase activity in serum of obese children is decreased and that it can be increased by reducing their body weight.

Abstract: The basal chordate Botryllus schlosseri undergoes a natural transplantation reaction governed by a single, highly polymorphic locus called the fuhc. Our initial characterization of this locus suggested it encoded a single gene alternatively spliced into two transcripts: a 555 amino acid–secreted form containing the first half of the gene, and a full-length, 1008 amino acid transmembrane form, with polymorphisms throughout the ectodomain determining outcome. We have now found that the locus encodes two highly polymorphic genes which are separated by a 227 bp intergenic region: first, the secreted form as previously described, and a second gene encoding a 531 amino acid membrane-bound gene containing three extracellular immunoglobulin domains. While northern blotting revealed only these two mRNAs, both PCR and mRNA-seq detect a single capped and polyadenylated transcript that encodes processed forms of both genes linked by the intergenic region, as well as other transcripts in which exons of the two genes are spliced together. These results might suggest that the two genes are expressed as an operon, during which both genes are co-transcribed and then trans-spliced into two separate messages. This type of transcriptional regulation has been described in tunicates previously; however, the membrane-bound gene does not encode a typical Splice Leader (SL) sequence at the 5′ terminus that usually accompanies trans-splicing. Thus, the presence of stable transcripts encoding both genes may suggest a novel mechanism of regulation, or conversely may be rare but stable transcripts in which the two mRNAs are linked due to a small amount of read-through by RNA polymerase. Both genes are highly polymorphic and co-expressed on tissues involved in histocompatibility. In addition, polymorphisms on both genes correlate with outcome, although we have found a case in which it appears that the secreted form may be major allorecognition determinant.

Spectrometry of the Earth using Neutrino Oscillations

Abstract: The unknown constituents of the interior of our home planet have provoked the human imagination and driven scientific exploration. We herein demonstrate that large neutrino detectors could be used in the near future to significantly improve our understanding of the Earth's inner chemical composition. Neutrinos, which are naturally produced in the atmosphere, traverse the Earth and undergo oscillations that depend on the Earth's electron density. The Earth's chemical composition can be determined by combining observations from large neutrino detectors with seismic measurements of the Earth's matter density. We present a method that will allow us to perform a measurement that can distinguish between composition models of the outer core. We show that the next-generation large-volume neutrino detectors can provide sufficient sensitivity to reject outer core models with large hydrogen content and thereby demonstrate the potential of this novel method. In the future, dedicated instruments could be capable of distinguishing between specific Earth composition models and thereby reshape our understanding of the inner Earth in previously unimagined ways.
A New Laparoscopic Surgical Procedure to Achieve Sufficient Mesorectal Excision in Upper Rectal Cancer

Abstract: Objective. Mesorectal excision corresponding to the location of a tumor, termed tumor-specific mesorectal excision (TSME), is commonly performed for resection of upper rectal cancer. We devised a new laparoscopic procedure for sufficient TSME with rectal transection followed by mesorectal excision. Operative Technique. After mobilization of the sigmoid colon and ligation of inferior mesenteric vessels, we dissected the mesorectum along the layer of the planned total mesorectal excision. The rectal wall was carefully separated from the mesorectum at the appropriate anal side from the tumor. After the rectum was isolated and transected using an endoscopic linear stapler, the rectal stump drew immediately toward the anal side, enabling the mesorectum to be identified clearly. In this way, sufficient TSME can be performed easily and accurately. This technique has been successfully conducted on 19 patients. Conclusion. This laparoscopic technique is a feasible and reliable procedure for achieving sufficient TSME. 1. Introduction Total mesorectal excision (TME) is recognized as an extremely important surgical technique for the prevention of local recurrence of rectal cancer [1–3]. On the other hand, TME is not necessarily applicable in every case of rectal cancer: for upper rectal cancer, mesorectal excision for limited lengths of 5?cm from a tumor toward the anal side is widely conducted, and this method is reportedly associated with adequate rates of cure [4, 5]. This technique is referred to as partial mesorectal excision (PME), but rather should be called tumor-specific mesorectal excision (TSME) reflecting its correspondence to the localization or T-stage of the tumor [5]. In a narrow pelvic cavity, performing sufficient TSME is difficult, and there is a risk of local recurrence when TSME is inadequate [6–8]. Whether surgery is performed laparoscopically or via a conventional open route, TSME is usually conducted obliquely to the anal side, introducing unnecessary rectal resection which may lead to postoperative bowel malfunction [9]. In addition, there is of the potential for slippage of the TSME between the right and left sides of the rectal wall. Particularly in the case of laparoscopic surgery, straight and sharp dissection of the mesorectum is difficult to perform and the dissection line is likely to be in zigzags. Of course, TSME shifting toward the oral side from the starting line is inappropriate and should be strictly avoided in order to prevent local recurrence (Figure 1).
