Research ArticleOpen accessEvery word in the titleSilicone Modeling of the Interior Spaces of Hollow Organs: Use in Dog and Manatee Respiratory Tract and in a Beef HeartCharles J. Grossman, Richard Hamilton, Lisa A. Close-Jacob et al.Problem statement: The mechanism, by which the Florida manatee (Trichechus manatus latirostris) vocalizes, remains unknown because the manatee larynx does not contain true vocal cords. Since sound can be generated when air passes through a narrow respiratory structure we needed to visualize the internal anatomy of manatee respiratory tract to locate any candidate regions for study. Approach: To visualize the … …OnLine Journal of Biological Sciences, Vol. 11, Issue 1 · 6 Jul 2011 · 7,804 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Reproductive Tract of the Males of the Zoophytophagous Predator Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) with Different Diets and AgesWalkymario de Paulo Lemos, Rafael Coelho Ribeiro, Francisco de Sousa Ramalho et al.Abstract: Problem statement: Brontocoris tabidus (Signoret) (Heteroptera: Pentatomidae) is a common and important species for the biological control of defoliating Lepidoptera caterpillars. Although it has a predatory feeding habit, this species make use of plant resources, which are essential for the maintenance of its population in laboratory colonies as well as in the field during periods of prey shortage. Thus … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,421 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudies on Emergence of Drug Resistance in HIV Associated Bacterial Urinary Tract InfectionsS. D. Deokar, M. G. BodhankarProblem statement: This study was designed to document the prevalence of HIV associated urinary tract infections in Barshi Tahsil. Such studies had not been researched out before in this region. Approach: The study included samples from 123 HIV reactive and 40 HIV non-reactive patients. In both, mid stream samples were collected and processed to examine for bacterial opportunistic pathogens. The … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 8,472 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Classical Design Approach of Cascaded Controllers for a Traction ElevatorUko Victor Sorochi, Kamalu Ugochukwu Anamelechi, Nwokocha Doris Adaugo, Uko Ebenezer UgochukwuA traction elevator is a control system that can be driven by Direct Current (DC) motors. Premised on the reviewed literature, operations of control systems incorporated with DC motors are restrained by nonlinearities that deviate the controlled variables (position, speed, and torque) from the reference input. Controllers designed with appropriate gains annul the nonlinearities inhibiting the operation of a traction … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 3 · 16 Aug 2023 · 6,029 accessesView PDFCite
Case ReportOpen accessEvery word in the titleActinomyces Odontolyticus with Klebsiella and Bacteroides Presenting as Facio-Cervical Abscess with Extension to Scalp and no Sinus TractTanveer Mir, Anita Choudhary, Anshu Wadehra et al.Actinomycosis is a rare infectious bacterial disease caused by various Actinomyces species. Being very rare, Actinomyces is easily misdiagnosed. Actinomyces are common commensals of the oral cavity which predispose to local infections. We report a case of a 67-year-old female who initially presented with swelling of the left sided face which later on proved to be a mixed infection with … …American Journal of Infectious Diseases, Vol. 15, Issue 2 · 14 Jun 2019 · 7,243 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRapid Real Time PCR Based Detection of Cell Count in Case of Urinary Tract InfectionPoulomi Nandy, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriMicrobial identification and antimicrobial susceptibility testing methods currently used in clinical microbiology laboratories require at least two to three days because they rely on the growth and isolation of micro-organisms. This long, but necessary, delay has enormous consequences on prophylactic usage of antimicrobial drugs. This study was an attempt to reduce this detection time span. Taq Man Real Time PCR … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 22 Jun 2013 · 8,217 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetection of Extended-Spectrum β Lactamases and AmpC β-Lactamase Production in Escherichia coli Causing Urinary Tract Infection among HIV and Non-HIV PatientsPadmavathy Kesavaram, Padma Krishnan, Rajasekaran SikhamaniProblem statement: Opportunistic infections have been documented as a leading cause of morbidity among HIV patients. Gram negative pathogens that elaborate beta-lactamases have been reported to be associated with increased morbidity and mortality, especially amongst immunocompromised patients on intensive care and high-dependency units. The most common mechanism of β-lactam drug resistance in Escherichia coli include ESBL, AmpC production. Approach: In … …Current Research in Medicine, Vol. 2, Issue 1 · 18 Aug 2011 · 7,837 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRespiratory Tract-Widening Effects of Dihydroartemisinin in Wistar Albino RatsUtoh-Nedosa Uchechukwu, Njoku Goddy, S. Nedosa Kenechi et al.Problem statement: Artemisinin-based anti-malarials are currently widely used in Asia and Africa. Not much is known about the systemic effect of dihydroartemisinin. This study therefore examine the effect of dihydroartemisinin on the lungs of Wistar albino rats. Approach: Five dosages of Dihydroartemisinin (DHA) were administered by oral intubation for 5 days to 5 test and 4 control Wistar albino rats. … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 2 · 17 Aug 2011 · 7,517 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Alloxan-Diabetes on Gastrin-Releasing Peptide (GRP) Immunoreactivity in the Gastrointestinal Tract, of Sprague Dawley Rats and How This May Affect Some of the Diabetic ComplicationsEdward O. Uche-Nwachi, Camille V. MitchellGastrin-releasing peptide (GRP) is the mammalian analogue of bombesin. Both neuroendocrine peptides have similar distribution, functions and immunoreactivity. The immunoreactivity for GRP has been demonstrated in the esophagus, stomach and small intestine. This peptide is reported to have various biological and pharmacological properties, which include the release of gastrointestinal hormones, control of satiety, gastrointestinal motility and stimulation of cellular proliferation … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 7,254 accessesView PDFCite
Literature ReviewOpen accessIn the keywordsDiagnostic Imaging of Gastrointestinal Tumours in Dogs and Cats: A ReviewFrancesco Simeoni, Francesca Del Signore, Rossella Terragni et al.Gastrointestinal tract tumours in dogs and cats are characterized by non-specific clinical presentation and laboratory abnormalities, but require fast identification, characterization and staging. Imaging techniques play a key role in the diagnostic process of these diseases in routine veterinary practice. Survey and contrast radiography may indicate primary or secondary signs of gastric or intestinal neoplasia such as a wall mass, … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 2 · 15 Apr 2020 · 9,839 accessesView PDFCite
