Fifteen strains of chlamydial agents, 2 Chlamydia trachomatis and 13 Chlamydia psittaci, were tested for plaque formation on chick embryo fibroblast cells. C. trachomatis strains did not form plaques; 12 strains of C. psittaci did form plaques and 1 strain did not. The distribution of plaque sizes with C. psittaci strains was studied and it was found that the 12 strains could be tentatively gro...

Using loan-level data from Mexico, we study the relationship between the organizational structure of banks and the terms of lending to small businesses. We find that banks with decentralized lending structures – where branch managers have autonomy over the terms of lending – give larger loans to small firms and those with more "soft information". However, decentralized banks are also more respo...

We consider the problem of concurrent portfolio losses in two non-overlapping credit portfolios. In order to explore the full statistical dependence structure of such portfolio losses, we estimate their empirical pairwise copulas. Instead of a Gaussian dependence, we typically find a strong asymmetry in the copulas. Concurrent large portfolio losses are much more likely than small ones. Studyin...

In winter 1383, the center for Research of Majlis Shura Islamic of Iran (CRMSII) published a proposal on the logic of the prevailing profit rate that the commercial banks pay/charge on long-term bank loans requiring the executive branch of Islamic Republic to lower the average rate of profit by 4.5 percent within 18 months of passage of the bill by Majlis, to reduce government budget defi...

The present studies were conducted to assess the antiproliferative effects of dexamethasone (DEX) in murine, rat, and xenograft tumor models and to determine if this kinetic response could be correlated with the level of cytosolic glucocorticoid receptors. Saturable DEX receptors were determined by the dextran-coated charcoal competitive-binding assay, and the antiproliferative effects of DEX w...

Finance and Growth at the Firm Level: Evidence from SBA Loans* We analyze linked databases on all Small Business Administration (SBA) loans, on all SBA lenders, and on all U.S. employers to estimate the effects of financial access on employment growth. Our methods combine regressions with matching on firm age, size, industry, year, and employment history, and with instrumental variables capturi...

microfinance, banking to the poor, is a recent global phenomenon introduced as a way for combating the poverty in the 1970’s. before that the poor were not allowed access to credit and loans due to the widespread belief that the poor could not repay loans. but microfinance movement with financial innovations reduced the costs and risks of lending to poor households, and presented as tool for re...

The superantigen staphylococcal enterotoxin A (SEA) binds to major histocompatibility complex (MHC) class II molecules at two sites on either side of the peptide groove. Two separate but cooperative interactions to the human class II molecule HLA-DR1 were detected. The first high affinity interaction to the DR1 beta chain is mediated by a zinc atom coordinated by H187, H225, and D227 in SEA and...

Introduction: Seasonal variation of benign paroxysmal positional vertigo (BPPV) presentation has been reported, with higher rates in months associated times lower serum vitamin D levels. The purpose this study was to examine the association between timing hip fracture patients BPPV. Methods: A retrospective review (2013 2019) adult performed at a tertiary care academic center identify due groun...
