To address the source of infection in humans and public health importance of Giardia duodenalis parasites from animals, nucleotide sequences of the triosephosphate isomerase (TPI) gene were generated for 37 human isolates, 15 dog isolates, 8 muskrat isolates, 7 isolates each from cattle and beavers, and 1 isolate each from a rat and a rabbit. Distinct genotypes were found in humans, cattle, bea...

Efficient production testing is frequently hampered because (cores in) current complex digital circuit designs require too large test sets, even with powerful ATPG tools that generate compact test sets. Built-In Self-Test approaches often suffer from fault coverage problems, due to randomresistant faults, which can successfully be improved by means of Test Point Insertion (TPI). In this paper, ...

In proliferating cells, a transition from aerobic to anaerobic metabolism is known as the Warburg effect, whose reversal inhibits cancer cell proliferation. Studying its regulator pyruvate kinase (PYK) in yeast, we discovered that central metabolism is self-adapting to synchronize redox metabolism when respiration is activated. Low PYK activity activated yeast respiration. However, levels of re...

The assemblages of Giardia duodenalis in 25 children with and 25 children without diarrhoea and 24 adults with gastrointestinal symptoms in South India were determined. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) targeting the glutamate dehydrogenase (gdh), β-giardin and triosephosphate isomerase (tpi) genes was used. The tpi PCR was the most sensitive and dete...

Giardia duodenalis is one of the most prevalent enteroparasites in children. This parasite produces several clinical manifestations. The aim of this study was to determine the prevalence of genotypes of G. duodenalis causing infection in a region of southeastern Mexico. G. duodenalis cysts were isolated (33/429) from stool samples of children and molecular genotyping was performed by polymerase...

The first serological test for syphilis, developed by Wassermann, Neisser, and Bruck (1906), was a complement-fixation test for reagin activity. Many tests for reagin activity have been developed since then, including the Kline, Kahn, Hinton, Kolmer, Mazzini, and VDRL slide tests. However, none of these is absolutely specific for syphilis. The VDRL slide test (Harris, Rosenberg, and Riedel, 194...

The pathogenic treponemes, T. pertenue and T. pallidum, produce similar antibodies in the serum of a person infected with either organism. Thus sera from patients with yaws react similarly to sera from syphilitic patients in the conventional tests for syphilis and in the Treponema pallidum immobilization (TPI) test. The most recent test developed for the detection of syphilis is the fluorescent...

This paper presents a model predictive control (MPC) of a utility interactive three phase inverter (TPI) for a photovoltaic (PV) system at commercial level. The proposed model uses phase locked loop (PLL) to synchronize the TPI with the power electric grid (PEG) and performs MPC control in a dq reference frame. TPI model consists of a boost converter (BC), maximum power point tracking (MPPT) co...

Paracoccidioides brasiliensis is an important fungal pathogen. The disease it causes, paracoccidioidomycosis (PCM), ranges from localized pulmonary infection to systemic processes that endanger the life of the patient. Paracoccidioides brasiliensis adhesion to host tissues contributes to its virulence, but we know relatively little about molecules and the molecular mechanisms governing fungal a...
