Chronic hypoxemia is known to cause peripheral neuropathy (PNP) in chronic obstructive pulmonary disease (COPD) patients. We aimed to know how often PNP is encountered in such patients and the changes in the central nervous system (CNS) if any. We enrolled 32 patients (30 M, 2 F; mean age +/- SD: 61.5 +/- 8.8 years) with COPD into the study. PaO2 > or = 55 mmHg was considered as the cut-off val...

LetR be a ring andM a rightR-module with S= End(MR). The moduleM is called almost principally quasi-injective (or APQ-injective for short) if, for any m∈M, there exists an S-submodule Xm of M such that lMrR(m) = Sm ⊕ Xm. The module M is called almost quasiprincipally injective (or AQP-injective for short) if, for any s∈ S, there exists a left ideal Xs of S such that lS(ker(s)) = Ss ⊕ Xs. In thi...

By a well known theorem of K. Morita, any equivalence between full module categories over rings R and S, are given by a bimodule RPS , such that RP is a finitely generated projective generator in R-Mod and S = EndR(P ). There are various papers which describe equivalences between certain subcategories of R-Mod and S-Mod in a similar way with suitable properties of RPS . Here we start from the o...

In this paper certain injectivity conditions in terms of extensions of monomorphisms are considered. In particular, it is proved that a ring R is a quasi-Frobenius ring if and only if every monomorphism from any essential right ideal of RR into R (N) R can be extended to RR. Also, known results on pseudo-injective modules are extended. Dinh raised the question if a pseudo-injective CS module is...

We introduce the concepts of lifting modules and (quasi-)discrete modules relative to a given left module. We also introduce the notion of SSRS-modules. It is shown that (1) if M is an amply supplementedmodule and 0→N ′ →N →N ′′ → 0 an exact sequence, then M isN-lifting if and only if it isN ′-lifting andN ′′-lifting; (2) ifM is a Noetherianmodule, then M is lifting if and only if M is R-liftin...

Brainstem auditory evoked response (BAER) is a reliable test for neonatal auditory and neurological dysfunction and it permits early diagnosis and rehabilitation. The purpose of this study is to demonstrate latencies of BAER in normal term neonates in order to obtain reference values in a university hospital. BAER was performed in the second day of life in 47 normal newborns (25 male, 22 female...

Brainstem auditory evoked responses (BAER) were longitudinally recorded prospectively in 18 term infants with neonatal hyperbilirubinemia (NHB) (total serum bilirubin > 15 mg/dl). Seven neonates had abnormal BAER. Wave complex IV-V was absent in eight recordings in NHB group while they were normal in the control group (p < 0.001). Prolongation of latency of waves I and V and interwave conductio...

We establish braided tensor equivalences among module categories over the twisted quantum double of a finite group defined by an extension of a group G by an abelian group, with 3-cocycle inflated from a 3-cocycle on G. We also prove that the canonical ribbon structure of the module category of any twisted quantum double of a finite group is preserved by braided tensor equivalences. We give two...

BACKGROUND Brainstem auditory evoked response has been an underused diagnostic modality in horses as evidenced by few reports on the subject. HYPOTHESIS/OBJECTIVES To describe BAER findings, common clinical signs, and causes of hearing loss in adult horses. ANIMALS Study group, 76 horses; control group, 8 horses. METHODS Retrospective. BAER records from the Clinical Neurophysiology Labora...
