Pediatric forearm fractures with tens: freedom of movements

Background: A prospective analysis of a case series of diaphyseal forearm fractures in children treated with titanium elastic nails is presented.  Methods: Between 2012 and 2014, 30 children aged 5-15 years with displaced diaphyseal forearm fractures underwent titanium elastic nailing. Both bones were fractured in 25 patients, four fractured only the radius, and one experienced ulna fracture. Eleven candidates had unstable irreducible fractures, 13 had loss of reduction, and six had open fractures. Titanium elastic nails were used to stabilize the fractures. All fractures were immobilized postoperatively with an above-elbow plaster slab for 2 weeks till the swelling is completely resolved followed by encouraging range of motion exercises.Results: Closed reduction and TENS was successful in 20 cases, including 15 double-bone fractures and five single-bone fractures. Open reduction was completed in four fractures of both bones, and in six single-bone open fractures. Bone union was achieved in all patients at an average of 7 weeks. The ROM of the forearms was evaluated using the Daruwalla grading criteria. Excellent results were reported in 96% without significant complications after a mean follow-up of 20 months.Conclusions: Titanium elastic nails fixation of pediatric forearm fractures revealed several advantages, a small incision for insertion, a low rate of complications, unhindered bone healing, and good clinical and radiological results thus achieving maximum range of motion at the earliest

Micropropagation of gum karaya (Sterculia urens) by adventitious shoot formation and somatic embryogenesis

Nodal explants from selected trees of gum karaya (Sterculia urens Roxb.) in the adult growth phase cultured on Murashige and Skoog (MS) medium supplemented with 6.62 μm N6-benzylaminopurine (BAP) produced an average of six adventitious shoots in 30 days. Shoots were rooted in vitro on 1/4-strength MS medium containing 9.82 μm indole-3-butyric acid. Nodulated callus was produced from hypocotyl explants cultured on MS medium supplemented with 4.52 μm 2,4-dichlorophenoxyacetic acid and 8.90 μm BAP. Somatic embryos developed when the nodulated callus was transferred to MS medium containing 0.45 μm thidiazuron (TDZ). TDZ treatment for 2 days gave the optimum response. Over 30% of the somatic embryos developed into plantlets when transferred to ¼-strength MS basal medium without any growth regulators. Plantlets produced from adventitious shoots and somatic embryos were acclimatized to ex vitro conditions and established in the field

Floral sexuality and breeding system in gum karaya tree, Sterculia urens

Comprehensive studies were carried out on phenology, floral sexuality, pollination biology, pollen-pistil interaction, breeding system and fruit and seed set on three populations of gum karaya tree (Sterculia urens). The species is andromonoecious and produces a large number of male and a limited number of bisexual (functionally female) flowers. The numbers of male and bisexual flowers varies not only between trees but also during the flowering period within a tree. Each male flower produces about 5000 fertile pollen grains. Neither in morphology nor in number, is there any difference between pollen grains in the bisexual and male flowers. However, pollen grains of bisexual flowers are completely sterile and incapable of siring any seeds. Their anthers, however, serve to attract pollinators; the emasculated bisexual flowers fail to do so. Thus S. urens is apparently andromonoecious but exhibits cryptic monoecy. That the species is self-incompatible was confirmed by controlled pollinations. The self-incompatibility is of the late-acting type and manifests after the entry of the pollen tube into the ovule. Apis indica is the only pollinator recorded by us and wind plays no role in pollination. The efficacy of pollination is low as only 56% of flowers were estimated to be pollinated. The pollen load on one-third the number of pollinated stigmas was lower than the number of ovules present. Fruit set under open pollination is poor and is highly variable from tree to tree (0.7-3.2%). Apart from pollination constraint, limited resource availability may also contribute to low fruit set

Concentration of uranium levels in groundwater

The uranium isotopes during their course of their disintegration decay into other radioactive elements and eventually decay into stable lead isotopes. The cause of environmental concern is the emanation of beta and gamma radiation during disintegration. The present study tends to estimate uranium in groundwater trapped in granite and gneiss rocks. Besides, the study aims at estimating the radiation during natural disintegration process. The water samples were collected and analyzed following inductively coupled plasma mass spectrometric technique while water sample collection was given to the regions of Kolar District, South India, due to the representation. The significant finding was the observation of very high levels of uranium in groundwater compared to similar assays reported at other nearby districts. Also, the levels were considerable to those compared to groundwater levels of uranium reported by other scientists. On the basis of this study, it was inferred that the origin of uranium was from granite strata and there was a trend of diffusion observed in the course of flow-path of water in the region

Building automation pipeline for diagnostic classification of sporadic odontogenic keratocysts and non-keratocysts using whole-slide images

The microscopic diagnostic differentiation of odontogenic cysts from other cysts is intricate and may cause perplexity for both clinicians and pathologists. Of particular interest is the odontogenic keratocyst (OKC), a developmental cyst with unique histopathological and clinical characteristics. Nevertheless, what distinguishes this cyst is its aggressive nature and high tendency for recurrence. Clinicians encounter challenges in dealing with this frequently encountered jaw lesion, as there is no consensus on surgical treatment. Therefore, the accurate and early diagnosis of such cysts will benefit clinicians in terms of treatment management and spare subjects from the mental agony of suffering from aggressive OKCs, which impact their quality of life. The objective of this research is to develop an automated OKC diagnostic system that can function as a decision support tool for pathologists, whether they are working locally or remotely. This system will provide them with additional data and insights to enhance their decision-making abilities. This research aims to provide an automation pipeline to classify whole-slide images of OKCs and non-keratocysts (non-KCs: dentigerous and radicular cysts). OKC diagnosis and prognosis using the histopathological analysis of tissues using whole-slide images (WSIs) with a deep-learning approach is an emerging research area. WSIs have the unique advantage of magnifying tissues with high resolution without losing information. The contribution of this research is a novel, deep-learning-based, and efficient algorithm that reduces the trainable parameters and, in turn, the memory footprint. This is achieved using principal component analysis (PCA) and the ReliefF feature selection algorithm (ReliefF) in a convolutional neural network (CNN) named P-C-ReliefF. The proposed model reduces the trainable parameters compared to standard CNN, achieving 97% classification accuracy

Influence of Particle Size of Enogen Feed High Amylase and Conventional Yellow Dent Corn on Finishing Pig Performance, Carcass Characteristics, and Stomach Ulceration

A total of 323 pigs (DNA 241 × 600; initially 109.8 lb) were used in an 83-d growth trial to evaluate the influence of particle size of Enogen Feed corn (Enogen, Syngenta Seeds, LLC, Downers Grove, IL) and conventional yellow dent corn on finishing pig performance. Pigs were randomly assigned to pens (9 pigs per pen) and pens were allotted by weight to 1 of 6 dietary treatments in a randomized complete block design with 6 pens per treatment. Treatments were arranged in a 2 × 3 factorial with main effects of corn source (Enogen Feed corn or conventional yellow dent) and 3 ground corn particle sizes (300, 600, or 900 microns). Overall, from d 0 to 83, there were no differences among corn sources observed for average daily gain (ADG), average daily feed intake (ADFI), and feed efficiency (F/G). As particle size of the diet decreased from 900 to 300 microns, ADG increased (linear, P = 0.018). Overall F/G improved (linear, P = 0.021) as corn particle size was decreased. In summary, reducing the particle size of the diet improves feed efficiency with no major differences between corn sources for overall pig performance

Hypothermia for encephalopathy in low and middle-income countries (HELIX): Study protocol for a randomised controlled trial

BACKGROUND: Therapeutic hypothermia reduces death and disability after moderate or severe neonatal encephalopathy in high-income countries and is used as standard therapy in these settings. However, the safety and efficacy of cooling therapy in low- and middle-income countries (LMICs), where 99% of the disease burden occurs, remains unclear. We will examine whether whole body cooling reduces death or neurodisability at 18-22 months after neonatal encephalopathy, in LMICs. METHODS: We will randomly allocate 408 term or near-term babies (aged ≤ 6 h) with moderate or severe neonatal encephalopathy admitted to public sector neonatal units in LMIC countries (India, Bangladesh or Sri Lanka), to either usual care alone or whole-body cooling with usual care. Babies allocated to the cooling arm will have core body temperature maintained at 33.5 °C using a servo-controlled cooling device for 72 h, followed by re-warming at 0.5 °C per hour. All babies will have detailed infection screening at the time of recruitment and 3 Telsa cerebral magnetic resonance imaging and spectroscopy at 1-2 weeks after birth. Our primary endpoint is death or moderate or severe disability at the age of 18 months. DISCUSSION: Upon completion, HELIX will be the largest cooling trial in neonatal encephalopathy and will provide a definitive answer regarding the safety and efficacy of cooling therapy for neonatal encephalopathy in LMICs. The trial will also provide important data about the influence of co-existent perinatal infection on the efficacy of hypothermic neuroprotection. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02387385.
