A prospective comparative study in the management of NeerтАЩs type II and type III proximal humerus fracture with proximal humerus nail versus proximal humerus internal locking system
Background: Proximal humerus fractures account for approximately 4-5 % of all the fractures and are next in occurrence to hip fractures and distal radius fractures in elderly population.Methods: A prospective study of 40 patients with NeerтАЩs type II and type III proximal humerus fracture, among which 20 were treated with proximal humerus nail and 20 with proximal humerus internal locking system at two Hospitals attached to J.J.M Medical College Davangere, Karnataka, India between September 2015 to December 2016. At final follow up results were assessed with constant shoulder scoring system.Results: In the PHN group, 8 patients (40%) showed excellent outcome, 8 patients (40%) showed good outcome and 4 patients (20%) showed fair outcome. Among the PHILOS group, 12 patients (60%) showed good outcome, 6 patients (30%) showed fair outcome and 02 patients (10%) with poor outcome.Conclusions: Proximal humerus nail for NeerтАЩs type II and type III proximal humerus fracture has better results compared to proximal humerus locking plate system with increased range of movements and restoring better shoulder biomechanics
Determination of growth inhibitors and toxins
Certain feedstuffs contain natural toxins that; at high
enough levels, are growth inhibitors and sometimes fatal to the
animal consuming them. Principal among these are: (a) Urease-an
enzyme found in raw soybean which produces toxicity through the
hydrolysis of urea to ammonia; (b) gosaypol-an endogenous toxin
present in the gland of cottonseed which persists during production
of the meal unless removed by a special process, or, unless,
the cotton seed is a glandless variety; (c) Isothiocyanatescyanogenic
glycosides are found in linseed and cassava; (d) aflatoxin
is a class of extremely potent toxins produced by the mould
Aspergillus flavus. Aflatoxin may be present in any materials
produced and stored under hot and humid conditions and is usually
found in groundnut cake, palm cake, copra cake and maize
Proximate composition analysis of feeds
The chemical composition of the feed gives its potential
nutritive value and hence, in the assessment of quality of a
feed the proximate principles are first determined. The Weende
proximate analysis system for analyzing animal feed includes the
determination of moisture (dry matter) ether extract (crude fat)
crude protein, ash, crude fibre and nitrogen free extract (NFE)
Determination of minerals
Mineral elements have a great diversity of uses within the
animal body. The prominence of each mineral element in body
tissues is closely related to its functional role. Calcium and phosphorus are too major mineral elements that must be present in adequate amounts in the feeds supplied. The amount of sodium chloride and potassium in certain feeds should also be ascertained to screen out feeds for feeding fish and shellfish
The Marquette Palliative Care System
Worldwide, major clinical barriers to effective palliative care are the absence of a. current data on symptom type and intensity; b. immediately accessible information on practical, affordable, and effective interventions; and c. self-sustaining systems to facilitate physician engagement in continuing palliative care. Our adaptable system, developed for Bangladesh and Nepal, addresses these barriers. A tele-home palliative care program facilitates home care, minimizes expense, and encourages efficient professional practitioner involvement employing two information technology tools: a patient cell-phone тАЬappтАЭ on the Android platform with a 15-item symptom questionnaire and an Internet website with health information sections for patients/families and for clinicians. The physician section contains a guide for patient symptom review, clinical practice palliative care guidelines, secured patient demographics, medical summaries, and current and past symptom reports along with prescription-writing capability. The system is managed by a local organization that registers patients and their physicians, instructs patients on the free downloadable application and completes their demographic and medical summaries, and arranges collection of a modest fee. The organization also ensures regular physician/clinic visits by the patient or by a family member with a patient phone check-in, at least every 2┬аweeks
Preparation of artificial diets for nutritional studies
The H 440 standard reference diet of Halver (1969) has*
proven satisfactory for use with a variety of species of fishes.
If this exact formula does not prove satisfactory for growth and
survival of the test fish, slight modifications of clearly
explained ingredient changes still permit meaningful comparisons
of the test fish results with other species
Determination of vitamins in feeds
The vitamins, though required in small amounts in the
diet, play major roles in growth, physiology and metabolism of
the animal. Their absence in the diet causes major deficiency
syndromes. Also, the vitamins should be present in optimum
levels in the diet; any excess in certain vitamins in the diet
causes pathological symptoms and inhibit growth. Therefore,
the determination of the amount of different vitamins present
in the diet is very important
Experimental Development of a Bat Inspired Obstacle Mapping System
This paper presents the development of an experimental method for obstacle detection using modified bat inspired navigation. Effective obstacle detection is vital to the efficient operation of many autonomous vehicles, mobile robotics and navigation systems. Varieties of sensors and sensor array combinations have been purposely developed to effectively detect and map obstacles and barriers during navigation [1][2]. Among these, ultrasonic sensors provide an inexpensive solution to distance and obstacle sensing. This is vital for industries such as automotive and transportation in which cost is a significant factor [3]. This work enhances the abilities of testing object classification capabilities of ultrasonic sensors through verification and proof of concept for bat-inspired, time of flight (TOF) based algorithms. Just as bats utilize acoustic echo to detect objects while navigating, this bat inspired system utilizes two static ultrasonic receivers and one central dynamic emitter. In our system, the electronic setup implemented was designed to activate a 40kHz emitter, capture the echo milliseconds later and incrementally move the emitter via the stepper motor. Upon activation of the emitter, the measurement device was triggered and the two distinct receiver signals were acquired. Receiver signals were then passed through a virtual low-pass filter and curve fitting algorithm in order to effectively and consistently determine the TOF values. Internal circuitry delays between trigger time and time of emission was accounted for through a test case with known orientation and speed of sound. Lastly the inherent nature of a diffuse detection surface permitted the detection of reflected signals from all emitter orientations. The experimental methodology developed in this research was successfully tested for detecting walls with a low cost ultrasonic emitter and receiver, setting a basis for analysis of future TOF based detection algorithms. The outcome of this research has the potential to provide effective barrier detection systems for autonomous navigation systems
Incidence of neurosensory deficits following surgical removal of mandibular third molars: a prospective clinical study
Background: The aim of this prospective study was to determine the incidences of inferior alveolar nerve and lingual nerve deficit following surgical removal of impacted mandibular third molars and to evaluate the risk factors responsible for these postoperative neurosensory deficits.Methods: A total of 80 patients who reported to department of oral and maxillofacial surgery, Meenakshi Ammal Dental College, Chennai, Tamil Nadu, India requiring surgical removal of impacted mandibular third molar were included in this cross-sectional study. Standard surgical procedure was performed. All patients were reassessed one week post-surgery. Subjectively reported altered sensations were recorded and objective assessments were performed with light touch test, two-point discrimination threshold and pin-pick pain threshold. The collected data was analyzed using the chi square test to find out any clinical relevance.Results: There was no inferior alveolar nerve related neurosensory deficits and 6 (7.5%) resulted in lingual nerve related neurosensory deficits. The incidence of LN deficit for mesioangular, horizontal, distoangular was 1.3%, 3.8% and 2.5% respectively. Type of impaction assumed a mild statistical significance (p = 0.050).Conclusions: This study highlights the importance of careful preoperative clinical and radiographic assessment of patients where third molar surgery is planned. The surgical technique of third molar removal is also likely to have great impact on the outcome
