Somatic mutation rates scale with time not growth rate in long-lived tropical trees.

The rates of appearance of new mutations play a central role in evolution. However, mutational processes in natural environments and their relationship with growth rates are largely unknown, particular in tropical ecosystems with high biodiversity. Here, we examined the somatic mutation landscapes of two tropical trees, (slow-growing) and (fast-growing), in central Borneo, Indonesia.

Effect of gender on spect myocardial perfusion imaging results in Egypt.

Background: Globally, Ischemic heart disease (IHD) is considered a leading cause of mortality and morbidity affecting men than women. The more the population ages, the more the prevalence. There was a concern about improper referral of women to MPI testing.

Comparing modeling methods of genomic prediction for growth traits of a tropical timber species, .

Introduction: is a commercially important tropical tree species grown for timber and oil. It is amenable to plantation forestry due to its fast initial growth. Genomic selection (GS) has been used in tree breeding studies to shorten long breeding cycles but has not previously been applied to .

Cubital tunnel syndrome of the ulnar nerve caused by an epineural ganglion cyst: a case report and review of the literature.

Background: The ulnar nerve has a long and complex anatomical course, originating from the brachial neural plexus in the neck with nerve trunk formation at the posterior neck triangle, and on to the axilla. This intricate anatomical pathway renders the nerve susceptible to compression, direct injury, and traction throughout its course. Compression of the ulnar nerve is the second most common compression neuropathy of the median nerve adjacent to the wrist joint, after carpal tunnel syndrome.

Cecal perforations due to descending colon obstruction (closed loop): a case report and review of the literature.

Background: Cases of large bowel closed-loop phenomenon with cecal perforation are extremely rare, especially when extracolonic epiploic appendage and peritoneal bands are the cause.

Lp- and Ls-Norm Distance Based Robust Linear Discriminant Analysis.

Recently, L1-norm distance measure based Linear Discriminant Analysis (LDA) techniques have been shown to be robust against outliers. However, these methods have no guarantee of obtaining a satisfactory-enough performance due to the insufficient robustness of L1-norm measure. To mitigate this problem, inspired by recent works on Lp-norm based learning, this paper proposes a new discriminant method, called Lp- and Ls-Norm Distance Based Robust Linear Discriminant Analysis (FLDA-Lsp).

Nuclear and chloroplast DNA phylogeography reveals Pleistocene divergence and subsequent secondary contact of two genetic lineages of the tropical rainforest tree species Shorea leprosula (Dipterocarpaceae) in South-East Asia.

Tropical rainforests in South-East Asia have been affected by climatic fluctuations during past glacial eras. To examine how the accompanying changes in land areas and temperature have affected the genetic properties of rainforest trees in the region, we investigated the phylogeographic patterns of a widespread dipterocarp species, Shorea leprosula. Two types of DNA markers were used: expressed sequence tag-based simple sequence repeats and chloroplast DNA (cpDNA) sequence variations.

Molecular database for classifying Shorea species (Dipterocarpaceae) and techniques for checking the legitimacy of timber and wood products.

The extent of tropical forest has been declining, due to over-exploitation and illegal logging activities. Large quantities of unlawfully extracted timber and other wood products have been exported, mainly to developed countries. As part of the export monitoring effort, we have developed methods for extracting and analyzing DNA from wood products, such as veneers and sawn timbers made from dipterocarps, in order to identify the species from which they originated.

Suppression of transplant immunity in experimental trichinellosis.

Skin allograft rejection in Balb/c and C57BL/6J mice following experimental infection with 300 larvae of Trichinella spiralis or Trichinella pseudospiralis was studied. Skin grafts from normal C57BL/6J mice were transplanted to infected Balb/c mice and vice versa at days 3, 10, 20 and 30 post-infection. The clinical criteria for graft rejection, scarring and graft falling, were followed.

Characterization of a synthetic peptide mimicking trypsin-cleavage site of rotavirus VP4.

A synthetic peptide corresponding to the trypsin cleavage site on the 84 k protein of bovine rotavirus was synthesized (VP4-peptide). This synthetic peptide could be cleaved by trypsin and therefore possessed the enzyme binding site present on the authentic protein. Further proof that this peptide mimicks the authentic trypsin cleavage site was the specific reaction of anti-peptide serum with the 84 k protein.

Cyclosporine A versus cyclosporine G: a comparative study of survival, hepatotoxicity, nephrotoxicity, and splenic atrophy in BALB/c mice.

Our group has previously shown that cyclosporine A (CSA) but not cyclosporine G (CSG) causes splenic atrophy in a BALB/c mouse model. We have now extended our studies to observations of the effect of the two drugs on other parenchymal organs and on the nervous system. Groups of mice (N = 30) were given 150 mg/kg per day of either CSA or CSG and were compared to two control groups.

Production of a monoclonal antibody reactive with human dendritic reticulum cells and its use in the immunohistological analysis of lymphoid tissue.

A murine monoclonal antibody (designated R4/23) which reacts strongly with human dendritic reticulum cells (DRC) is described. Immunoperoxidase staining of tissue cryostat sections revealed that this antibody reacts strongly with DRC in lymphoid follicles (both primary and secondary), and also weakly with marginal zone splenic B cells and with some peripheral follicular mantle B lymphocytes in lymph node cortical follicles. The value of antibody R4/23 is that it allows the distribution of DRC in reactive and neoplastic lymphoid tissue to be clearly delineated.

Preparation of peroxidase: antiperoxidase (PAP) complexes for immunohistological labeling of monoclonal antibodies.

The production of mouse peroxidase:antiperoxidase (PAP) complexes suitable for immunohistological use in conjunction with monoclonal antibodies is described. Three approaches were explored: 1) production of conventional polyclonal PAP complexes; 2) conversion of rabbit PAP to "pseudo-mouse PAP" by incubation with monoclonal mouse anti-rabbit immunoglobulin; 3) formation of PAP complexes from monoclonal mouse antiperoxidase. PAP complexes prepared by the latter technique gave the best immunohistological labeling reactions, being stable on storage and compatible with a wide range of human monoclonal antibodies.
