Mouth Breathing During Exercise May Lead To many Health Deseases

One of the most basic requirements for an effective exercise session is better oxygenation of yourmuscular tissues and organs. You can actually find out how well your tissues are being oxygenated byhow you emit.While breathing is a fundamental natural function of human beings, it can be negatively influenced bymany components of modern living such as accent, sitting at a desk all day, and excessive talking. In fact,about 80 percent of the Western population breathes incorrectly.Nasal breathing has a number of physiological advantages for your health and your fitness. The amount ofbenefit you derive from your exercise efforts is largely manipulated by your breathing habits, which standupon your performance, endurance, post-exercise energy levels, and even your ability to metabolize fat.Most people overbreathe – in other words, they chronically hyperventilate. Distinctive characteristics ofoverbreathing include mouth breathing, upper chest breathing, sighing, noticeable breathing during sleep,and taking large breaths prior to the oral presentation. Overbreathing during exercise can cause a numberof harmful effects. The means to forbid this, is to "retrain" your nose to do the job it was designed toanswer

Preliminary Investigation of Beagle Dog as Substitute for Humans in Bioequivalence Studies

Purpose: To assess the suitability of beagle dog as an animal model for the evaluation of formulations in bioavailability and bioequivalence studies.Methods: A generic cetirizine 10 mg tablet formulation was compared with another reference formulation using beagle dog as animal model. A crossover oral comparative bioavailability study was conducted on cetirizine tablet 10 mg in healthy, male dogs under fasting conditions. The  formulations were administered orally with the aid of water. Serial blood samples were collected from pre-dose to 48.0 h post-dose and plasma concentrations of cetirizine were determined using validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) analytical method. Pharmacokinetic parameters were calculated using  non-compartmental analysis while bioavailability was assessed using an analysis of variance (ANOVA) model for humans and dogs.Results: Cetirizine plasma concentrations in dog were comparatively  higher, in relation to human plasma concentrations, due to the smaller blood volume in former. There was a delay in time to reach maximum plasma concentration (Tmax) in dog. Cetirizine formulations were found to be bioequivalent in either of the species (dog and human). The ratio (test\reference) of least-squares mean for area under plasma concentration curve from time zero to last detectable concentration (AUC0-t), area under plasma concentration curve extrapolated to infinity (AUC0-‡ ) and maximum plasma concentration (Cmax), calculated for the dogs were comparable to those for humans. AUC0-t, AUC0-‡ and Cmax ratios ranged within 92.81 - 106.80 % for dogs and 95.43 . 104.84 % for humansConclusion: The results suggest that beagle dogs can be used in place of humans in bioequivalence tests on generic products of cetirizine.Keywords: Cetirizine, Beagle dog, Bioavailability, Bioequivalence, Pharmacokinetics, Noncompartmenta

Antiangiogenic activity of zinc and zinc-sorafenib combination using the chick chorioallantoic membrane assay: a descriptive study

Background: Zinc, a trace element, is known for downregulating several proangiogenic growth factors and cytokines. However, its antiangiogenic activity is not adequately studied. The present study was aimed to evaluate the possible antiangiogenic activity of zinc via the chick chorioallantoic membrane (CAM) assay. Also, the antiangiogenic activity of the combination therapy of zinc with various doses of sorafenib, a tyrosine kinase inhibitor, was evaluated.Methods: A pilot study was initially conducted so as to select suitable doses of zinc and sorafenib. The antiangiogenic activity after combining zinc 2.5 μg/embryo with sorafenib 1, and 2 μg/embryo was also evaluated. The antiangiogenic activity was quantified in terms of total length of blood vessels, number of junctions, number of branching points, and mean length of the blood vessels.Results: Zinc 2.5 μg/embryo showed significant (p 0.05) to that of sorafenib 2 μg/embryo.Conclusions: Zinc caused significant antiangiogenic activity in the CAM assay. The lack of addition/synergism in the zinc-sorafenib combination could have been due to the variability in the dose/ratio selection. Addition of zinc to sorafenib therapy could improve treatment tolerability, reduce cost of therapy, and reduce the emergence of drug resistance. Future mechanistic studies could identify the exact pharmacodynamics of zinc as an angiogenesis inhibitor

An unusual cause of acute encephalopathy: D-lactic acidosis secondary to short bowel syndrome

Background: Blood D-lactate levels increase in short bowel syndrome (SBS) and may lead to neurological manifestations. Clinical Description: A 5-year-old boy, postoperative case of SBS, presented with loose stools, generalized weakness, and lethargy for 2 days. The child had undergone significant intestinal resection in the past. On examination, he had some dehydration, and was drowsy, but arousable. Remaining examination was normal. Metabolic abnormalities detected included metabolic acidosis (pH of 7.1, HCO3 7 mmol/L), high anion gap (20 mmol/l), and normal lactate levels (2 mmol/L). Other baseline investigations were normal. He was treated as a case of acute gastroenteritis with some dehydration and metabolic acidosis and improved. He was discharged after 5 days. After 2 months, he was readmitted with drowsiness and unsteady gait. This time there was no diarrhea or dehydration. Investigations again revealed severe metabolic acidosis, high anion gap, and normal lactate levels. Management: We considered SBS induced D-lactate encephalopathy but were unable to prove it by assay due to unavailability of tests. The child was kept nil per orally and given bicarbonate infusion, on which he showed dramatic improvement. He was also given a low carbohydrate diet and oral metronidazole. The family was counseled at discharge 5 days later regarding dietary modifications and microsupplementation. The patient had 6 admissions for D-lactic encephalopathy over 4 years that coincided with dietary lapse. Conclusion: D-lactate acidosis is an underrecognized condition and its diagnosis and management is challenging. A high index of suspicion should be kept in patients with history of intestinal resection presenting with acute encephalopathy and unexplained metabolic acidosis

Influence of Poloxamer 188 on Design and Development of Second Generation PLGA Nanocrystals of Metformin Hydrochloride

The poly(D,L-lactide-co-glycolide) (PLGA) based second-generation nanocrystals prepared by modified nanoprecipitation method, is the method of choice for encapsulation of both lipophilic and hydrophilic drugs. In this study, nanoprecipitation technique was adopted to develop second generation nanocrystals of PLGA loaded with metformin HCl (MHc). Poloxamer 188 with three different concentrations (0.5, 0.75, 1% w/v) in combination with PLGA at 1, 2, 3% concentrations (w/v) successfully produced MHc loaded PLGA second generation nanocrystals. The effects of poloxamer 188, amphiphilic triblock copolymer on carrier particle size, surface morphology, polydispersity index, zeta potential, drug entrapment efficiency and drug release of nanoformulation were investigated. The optimized formulation of second-generation nanocrystals with concentrations 0.75% w/v poloxamer 188 and 2% w/v PLGA, could produce particle size of 114.6 nm, entrapment efficiency of 63.48% and drug release 80.23% at 12 h. A blank formulation with the same composition as optimized formulation without addition of poloxamer188 compared with optimized formulation, exhibited nanoparticles of larger mean particle size of 212.9 nm with entrapment efficiency of 68.47% and 50.5% drug release at 12 h. Transmission electron microscopy (TEM) analysis of the nanoformulations revealed that poloxamer188 greatly contributed to smooth, spherical morphology of nanosize polymeric nanoparticles. Further Fourier-transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC) studies on nanoformulation emphasized the significance of poloxamer188 in formulation and development of optimized MHc loaded PLGA nanosuspensions of second generation nanocrystals. In conclusion, the study emphasizes that poloxamer 188 was a versatile excipient, which played a pivotal role in producing nanosize carrier with high drug release profile of MHc loaded PLGA nanosuspensions of second generation nanocrystals

Effect of epidural clonidine on characteristics of spinal anaesthesia in patients undergoing gynaecological surgeries: A clinical study

Background and Aims: Combined spinal–epidural (CSE) anaesthesia is being increasingly used for effective post-operative analgesia. This study was designed to evaluate the effect of epidural clonidine on characteristics of spinal anaesthesia for gynaecological surgeries. Methods: This was a prospective randomised, double-blind, controlled study involving sixty patients belonging to American Society of Anesthesiologists Physical Status I and II who underwent gynaecological surgeries were randomly divided into clonidine (C) group and saline (S) group of thirty each. All patients received CSE anaesthesia. Ten minutes before subarachnoid block (SAB), Group C received clonidine 150 μg diluted to 5 ml in normal saline (NS) and Group S received NS epidurally. Hyperbaric bupivacaine (15 mg) was administered intrathecally for both groups after epidural injection. Sensory and motor block characteristics, analgesia, sedation and haemodynamics were observed. Statistical analysis was performed using appropriate tests. Results: Epidural clonidine produced faster onset (37.83 ± 8.58 s in Group C compared to 50.33 ± 8.80 s in Group S, P = 0.001) and prolonged duration of sensory block (241.17±18.65 minutes in group C compared to 150.33±19.16 minutes in group S, P = 0.001). Time for two segment regression of sensory block was193.67 ± 19.82 min in Group C and 109.33 ± 18.56 min Group S (P < 0.001). The duration of analgesia was 299.00 ± 43.38 min in Group C and 152.50 ± 21.04 min in Group S (P < 0.001). Haemodynamics and sedation scores were comparable between two groups. Conclusion: Administration of clonidine epidurally, 10 min before SAB, caused early onset and prolonged duration of motor blockade and analgesia, without any significant post-operative complication
