Viability Test of Fish Scales Collagen from Oshphronemus Gouramy on Osteoblast Cell Culture

Collagen is the potential material for periodontal tissue engineering. Fish scales can be used as an alternative source of collagen. The aim of this study was to examine the viability effect of collagen extracted from Oshphronemus gouramy scales on osteoblast cell culture. Osteoblast cell culture was made from the calvaria of baby Wistar rat. Collagen from Oshphronemus gouramy scales was extracted using 6% acetic acid. Collagen extract in different concentrations (0.00625 mg/ml, 0.0125 mg/ml, 0.025 mg/ml, 0.05 mg/ml, 0.1 mg/ml, 0.2 mg/ml, and 0.4 mg/ml) was added into osteoblast cell culture and incubated for 24 hours. MTT assay was performed to observe the viability of osteoblast cells. The data were statistically analyzed using ANOVA. The result showed that there were no significant differences in osteoblast cell viability after the administration of collagen extracted from Ohphronemus gouramy scales at various test concentrations (p>0.05). The percentage of viable cells of osteoblast was upper 50%. Oshphronemus gouramy scales can be a good alternative source of collagen because it has high viability against osteoblast cells.

ADJUSTING A SIMPLE CROP MODEL TO PREDICT MAIZE AND SORGHUM YIELD IN THE NORTHEAST BRAZIL

Rainfed agriculture in the Northeast of Brazil has been frequently affected by adverse weather and climate conditions. To anticipate the occurrence of crop failure, this study aimed to adjust a crop model for maize and sorghum crops at Serra Talhada and Araripina, both in the state of Pernambuco, Brazil. We used the water balance model of the CPTEC/INPE, including information to estimate crop failure, as proposed by Doorenbos and Kassam (1979). The analysis showed an agreement index of 80%, classified as very good, and an error below 30%, classified as acceptable, which suggests that the adjusted model can also produce satisfactory estimates for the whole Northeast region.
RESEARCH REGARDING TEXTURE OF WILD BOAR MEAT (SUS SCROFA FERUS) FROM FRASIN AREA, SUCEAVA

Meat provided from hunted species represent a nourishment alternative into a continuous expansiveness due to high nutritive properties, particular taste and continuous interest of husbandry industry, as well as consumers, for diversification (exploitation) of hunting resources at industrial level. So, the present research aimed to realise an intrinsic exploration of properties of meat gathered from hunted species which are specific to Romania, aiming to create a solid scientific base at national level for effectiveness of a correct information and realization of an accurate general picture on textural profile for this meat. To achieve the proposed target, determinations were carried out on a total number of 11 adult wild boar individuals (6 males and 5 females), gathered during some hunting parties organized in N-E area of Romania (Suceava Forestry Department, Frasin hunting fund). Inter-muscular variations of Warner Bratzler forces were described by great amplitude of data, being into interval 14.88 ÷ 86.63 N/cm2. So, mean tenderness of wild boar meat show for studies muscular samples a penetration force at breaking up of meat portion which varied into an interval inferiorly defined by 34.95±1.86 N/cm2 (m. Longissimus dorsi at females) and superiorly by 50.88±2.923 N/cm2 (m. Triceps brachii at males). By statistical analysis of existent differences, inside muscular group, between males and females for Warner Bratzler forces values were observed insignificant differences 75% from the total of effectuated tests.
A CLINICO PATHOLOGICAL STUDY ON RENAL CELL CARCINOMA IN A TERTIARY CARE CENTER

Background: The incidence of renal cell cancer (RCC) is increasing worldwide. However, scant information is available from the India, about its clinicopathological characteristics and survival outcomes. We prospectively analyzed data of patients suffering from RCC at Department Urology, Andhra Medical College & King George Hospital, Visakhapatnam, from October 2016 to January 2019 to generate information on these aspects. Materials and Methods: 32 patients treated between October 2016 to January 2019 were prospectively analyzed. Baseline characteristics, histopathological information, and survival outcomes were assessed. Results: The peak incidence of RCC was seen in 5th decade followed by 4th decade. The mean age at presentation was 52.45 years. Incidence is higher in males than in females with a ratio of 2.3:1. Smoking is associated with 45% of cases and hypertension in 34% of cases. The classic triad of RCC was seen only in 3 cases (8%). The mean tumour size was 10.25cm, range 5-19 cm. Only 5% of tumours were of size less than 4cm. 31% cases were in stage 1, 30% in stage 2 , 31 % in stage 3 and 8% in stage 4. Tumours are localized in 57%, locally advanced in 31 % and metastatic in 9%. Partial nephrectomy was done in only 2(5%) cases . Open Radical nephrectomy was done in 85% of cases. Post op biopsy showed Clear cell RCC variant in 22 (68%) and papillary carcinoma in 7 (21%), multilocular cyst in 1 (3%) and malignant fibrous histiocytoma in 1 case(3%). 75% of cases showed Fuhrman's grade 2 and 25% showed grade 3. Capsular invasion was seen in 21% and lymph nodal positivity for metastatic deposits in 12% and 34% showed necrosis. 5 Deaths were noted. 3 cases missed the follow up after surgery. All cases were advised 6 monthly ultrasound abdomen and chest X ray. Conclusions: Younger age at presentation, higher male–female ratio, lower proportion of asymptomatic patients, higher proportion of advanced stage at diagnosis, smoking & hypertension more commonly associated with RCC. Clear cell and papillary variants of RCC are more common.
BAYESIAN MULTIPLE TESTING UNDER SPARSITY FOR EXPONENTIAL DISTRIBUTIONS By KE LI A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA

of Dissertation Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy BAYESIAN MULTIPLE TESTING UNDER SPARSITY FOR EXPONENTIAL DISTRIBUTIONS By Ke Li August 2013 Chair: Malay Ghosh Major: Statistics Multiple testing problems are gaining increasing prominence in statistical research. The prime reason behind this is that there is a growing need for statisticians to analyze large data sets involving many parameters. Several methods to solve multiple testing problems have been introduced since the breakthrough paper by Benjamini and Hochberg in 1995. In this dissertation, we considers simultaneous testing of multiple exponential scale parameters under sparsity. Two general results provide thresholding conditions under which a given testing procedure achieves Bayesian optimality asymptotically. In particular, it is shown how multiple testing procedures of Benjamini and Hochberg’s, Efron and Tibshirani’s and Genovese and Wasserman’s can achieve this Bayesian optimality asymptotically. An alternative density for the scale parameter has also been considered.
Cheap Talk With Endogenous Conflict of Interest

In a cheap‐talk setting where the conflict of interest between sender and receiver is determined endogenously by the choice of parameters θ i for each agent i, conditions are provided that determine the sign of each agent's inverse demand for θ without assuming that the most informative equilibrium will necessarily be played in the cheap talk game. For two popular functional forms of payoffs, we derive analytically tractable approximations for agent i's demand for θ. In an application where the θi's are purchased on a competitive market, we provide conditions for a competitive equilibrium to feature maximal information transmission. In a principal–agent application where the agent's θ is set by the principal, our results show that information transmission will be partial. We consider extensions where: (1) the θ's are acquired covertly rather than overtly and (2) the θ's are traded after the sender has received the information.
REDUCING THE AGE AT FIRST CALVING THROUGH NUTRITIONAL MANIPULATIONS IN DAIRY BUFFALOES AND COWS: A REVIEW

Raising heifers is the most expensive component of the dairy farm operations. Poor growth rate resulting in delayed age at maturity in our local dairy animals further aggravates the situation. However, cost of heifer production can be reduced through better management, balanced feeding, use of performance modifiers and better health care. Selection for higher milk yield is likely to have a favorable impact on age at first calving. Yet, the current age at maturity in buffalo and Sahiwal cow can be reduced to 2 and 1.5 years, respectively, with better feeding and management. Protein and energy are the most critical nutrients affecting the weight and consequently age at puberty in heifers. Higher protein levels than current recommendations of NRC for dairy cattle can reverse the adverse effects of high plane of nutrition on udder development. Accelerated growth rate through performance modifiers to reduce the age at maturity is also helpful provided they do not adversely affect development of secretory tissue of udder for future milk production. Judicious use of balanced feed and performance modifiers has led to reduced age at puberty in exotic dairy heifers. These data can be used to device optimum heifer production systems in the country. However, for offering solid recommendations on optimum heifer production requires well planned research to see the effects of proteins, energy, minerals and other performance modifiers for economical heifer production in our country.
Diallel analysis involving heat-tolerant lines of tomato.

The critical factor in setting of tomato fruits is night time temperature, the optimum range being 15- 21°C. Fruit set in tomato is reduced markedly when average maximum day time and minimum night time tem- peratures go above 32 and 21°C, respectively. In the northwestern plains of India, temperature crosses the favor- able limit from the fourth week of April onwards, thereby reducing yield, lowering quality and shortening the fruit harvest span. The situation has forced tomato breeders to develop heat-tolerant cultivars and, therefore, the present study was conducted to determine the nature of gene action controlling various characters and to iden- tify a few good combiner genotypes that may be used in further breeding programmes for high temperature tol- erance. Highly significant general combining ability (gca) and specific combining ability (sea) variances indicat- ed the importance of both additive and non-additive gene action in the expression of all the characters. Howev- er, the ratio of components of genetic variance revealed the predominant role of non-additive gene actions in con- trolling total yield, marketable yield, number of fruits per plant, average fruit weight, days from fruit setting to turning stage, endosperm utilization efficiency, harvesting span, pericarp thickness, number of locules, lycopene content and titratable acidity. Therefore, heterosis breeding may be used to bring improvement in these traits. However, additive gene action played a major role in controlling days to anthesis, number of flowers per cluster and setting percentage per cluster. Hence, lines having good gca for these traits (LST-6, LCT-9, LST-42-1 and LST-65-2) may be hybridized and selection may be practiced in segregating generations to develop advanced gen- eration lines having high heat-tolerance ability.
The shallow-water fish assemblage of Isla del Coco National Park, Costa Rica: structure and patterns in an isolated, predator-dominated ecosystem

Fishes at Isla del Coco National Park, Costa Rica, were surveyed as part of a larger scientific expedition to the area in September 2009. The average total biomass of nearshore fishes was 7.8 tonnes per ha, among the largest observed in the tropics, with apex predators such as sharks, jacks, and groupers accounting for nearly 40% of the total biomass. The abundance of reef and pelagic sharks, particularly large aggregations of threatened species such as the scalloped hammerhead shark (up to 42 hammerheads ha-1) and large schools of jacks and snappers show the capacity for high biomass in unfished ecosystems in the Eastern Tropical Pacific. However, the abundance of hammerhead and reef whitetip sharks appears to have been declining since the late 1990s, and likely causes may include increasing fishing pressure on sharks in the region and illegal fishing inside the Park. One Galapagos shark tagged on September 20, 2009 in the Isla del Coco National Park moved 255km southeast towards Malpelo Island in Colombia, when it stopped transmitting. These results contribute to the evidence that sharks conduct large-scale movements between marine protected areas (Isla del Coco, Malpelo, Galápagos) in the Eastern tropical Pacific and emphasize the need for regional-scale management. More than half of the species and 90% of the individuals observed were endemic to the tropical eastern Pacific. These high biomass and endemicity values highlight the uniqueness of the fish assemblage at Isla del Coco and its importance as a global biodiversity hotspot. Citation: Friedlander, A. , B.J.

The Influence of Instagram Advertising on Destination Visit Intention

The current study examines the effect of social media-based (Instagram) influencer advertising, on advertising cognition, attitude towards a brand, brand beliefs, as well as intention to visit a tourist destination, on a sample of consumers in Gauteng Province of South Africa. The study sought to understand the mechanism by which influencer advertising affects consumer decision making. It proposed a unified social media influencer attitudemodel. To test the model, a survey questionnaire was administered among 404 Instagram users who have visited a destination of choice Instagram page. A confirmatory factor analysis (CFA) was undertaken to assess the dimensionality and validity of the measurement scale. The study used a path modelling technique to test the proposed hypotheses. The results of structural equation modelling (AMOS 25) indicated that the relationship between exposure to influencer advertising and brand belief was robust. However, exposure to influencer advertising showed a moderate positive effect on both advertising cognition and attitude towards the destination. Consequently, attitude towards the advertising (Ad), brand beliefs and brand attitude had a significant and positive effect on destination visit intention. While traditional models of advertising efficacy theorised that advertisements transform consumer attitudes mainly by modifying their brand beliefs, this study however found that consumers’ advertisement cognition, brand-linked beliefs, attitude towards the brand and their intention to visit a tourist destination of choice are influenced by their assessment of the of advertisement information.
RNA Polymerase II Accumulation in the Promoter-Proximal Region of the Dihydrofolate Reductase and γ-Actin Genes

ABSTRACT The carboxyl-terminal domain (CTD) of RNA polymerase II (Pol II) can be phosphorylated at serine 2 (Ser-2) and serine 5 (Ser-5) of the CTD heptad repeat YSPTSPS, and this phosphorylation is important in coupling transcription to RNA processing, including 5′ capping, splicing, and polyadenylation. The mammalian endogenous dihydrofolate reductase and γ-actin genes have been used to study the association of Pol II with different regions of transcribed genes (promoter-proximal compared to distal regions) and the phosphorylation status of its CTD. For both genes, Pol II is more concentrated in the promoter-proximal regions than in the interior regions. Moreover, different phosphorylation forms of Pol II are associated with distinct regions. Ser-5 phosphorylation of Pol II is concentrated near the promoter, while Ser-2 phosphorylation is observed throughout the gene. These results suggest that the accumulation of paused Pol II in promoter-proximal regions may be a common feature of gene regulation in mammalian cells.
AI Research, Replicability and Incentives

Deep Learning has produced some amazing results in Image Recognition, NLP, generative models, games, and more. It’s hard to argue with such progress. But as researchers are racing to beat each other’s state-of-the-art results, it has become increasingly difficult to decide if a paper is proposing something useful, overfitting a test set, or trying to achieve a flashy outcome for PR reasons. Survey papers and experience reports show that many papers are not replicable, statistically insignificant, or suffer from the narrative fallacy. I will link to some of these throughout the post. On social media, I regularly see posts (e.g. here or here) by practitioners complaining about not being able to get the same results a paper claimed to get.
The Effect of Serum and Follicular Fluid Vitamin D on Intracytoplasmic Sperm Injection Outcome

Vitamin D is a cholesterol derived, fat soluble, steroid substance present in the body. It plays an important role in the female reproductive system and regulating its functions. It is believed that vitamin D improves the endometrial thickness. The relationship between the level of vitamin D and fertilization, embryo quality and Intracytoplasmic sperm injection outcome remains controversial till now. The aim of the study to assess the relation of vitamin D levels in serum and follicular fluid with Intracytoplasmic sperm injection outcome. Eighty-eight women were enrolled in this study. They were classified according to the cause of infertility into case group with female factor and control group with male factor. All women were undergoing Intracytoplasmic sperm injection procedure. Serum and follicular fluid vitamin D levels were measured on the day of oocyte retrieval. It was found that no significant differences in either serum or follicular fluid level of vitamin D between the case and control groups and higher serum and follicular fluid levels of vitamin D are associated with better pregnancy rates after Intracytoplasmic sperm injection. Further studies on vitamin D in male are required to prove its role in the Intracytoplasmic sperm injection. The present study concluded that no significant differences in either serum or follicular fluid level of vitamin D between the case and control groups and higher serum and follicular fluid levels of vitamin D are associated with better pregnancy rates after Intracytoplasmic sperm injection.

Synthesis of lossless electric circuits based on prescribed Jordan forms

We advance here an algorithm of the synthesis of lossless electric circuits such that their evolution matrices have the prescribed Jordan canonical forms subject to natural constraints. Every synthesized circuit consists of a chain-like sequence of LC-loops coupled by gyrators. All involved capacitances, inductances and gyrator resistances are either positive or negative with values determined by explicit formulas. A circuit must have at least one negative capacitance or inductance for having a nontrivial Jordan block for the relevant matrix.
Long-term study of extreme giant pulses from PSR B0950+08 with AARTFAAC

We report on the detection of extreme giant pulses (GPs) from one of the oldest-known pulsars, the highly variable PSR B0950+08, with the Amsterdam-ASTRON Radio Transient Facility And Analysis Centre (AARTFAAC), a parallel transient detection instrument operating as a subsystem of the LOw Frequency ARray (LOFAR). During processing of our Northern Hemisphere survey for low-frequency radio transients, a sample of 275 pulses with fluences ranging from 42 to 177 kJy ms were detected in one-second snapshot images. The brightest pulses are an order of magnitude brighter than those previously reported at 42 and 74 MHz, on par with the levels observed in a previous long-term study at 103 MHz. Both their rate and fluence distribution differ between and within the various studies done to date. The GP rate is highly variable, from 0 to 30 per hour, with only two three-hour observations accounting for nearly half of the pulses detected in the 96 h surveyed. It does not vary significantly within a few-hour observation, but can vary strongly one from day to the next. The spectra appear strongly and variably structured, with emission sometimes confined to a single 195.3 kHz subband, and the pulse spectra changing on a timescale of order 10 min.
Photoreactivation of UV-induced damage to embryos of a planktonic copepod

UV irradiation damaged the embryos of the planktonic copepod Calanus sinicus. The hatch- ing rate was reduced, and the hatched larvae were deformed by the UV irradiation at unweighted intensities similar to those occurring naturally. However, the UV-induced damage was reduced by simultaneous irradiation with the visible light from a fluorescent lamp. This photoreactivation may play an important role in reducing the mortality of this species in the marine environment.
Formation Dynamics of Black- and White-Hole Horizons in an Analogue Gravity Model

We investigate the formation dynamics of sonic horizons in a Bose gas confined in a (quasi) one-dimensional trap. This system is one of the most promising realizations of the analogue gravity paradigm and has already been successfully studied experimentally. Taking advantage of the exact solution of the one-dimensional, hard-core, Bose model (Tonks–Girardeau gas), we show that by switching on a step potential, either a sonic, black-hole-like horizon or a black/white hole pair may form, according to the initial velocity of the fluid. Our simulations never suggest the formation of an isolated white-hole horizon, although a stable stationary solution of the dynamical equations with those properties is analytically found. Moreover, we show that the semiclassical dynamics, based on the Gross–Pitaevskii equation, conforms to the exact solution only in the case of fully subsonic flows while a stationary solution exhibiting a supersonic transition is never reached dynamically.
The Spinor-Tensor Gravity of the Classical Dirac Field

In this work, with the help of the quantum hydrodynamic formalism, the gravitational equation associated with the classical Dirac field is derived. The hydrodynamic representation of the Dirac equation described by the evolution of four mass densities, subject to the theory-defined quantum potential, has been generalized to the curved space-time in the covariant form. Thence, the metric of space-time has been defined by imposing the minimum action principle. The derived gravity shows the spontaneous emergence of the “cosmological” gravity tensor (CGT), a generalization of the classical cosmological constant (CC), as a part of the energy-impulse tensor density (EITD). Even if the classical cosmological constant is set to zero, the CGT is non-zero, allowing a stable quantum vacuum (out of the collapsed branched polymer phase). The theory shows that in the classical macroscopic limit, the general relativity equation is recovered. In the perturbative approach, the CGT leads to a second-order correction to Newtonian gravity that takes contribution from the space where the mass is localized (and the space-time is curvilinear), while it tends to zero as the space-time approaches the flat vacuum, leading, as a means, to an overall cosmological constant that may possibly be compatible with the astronomical observations. The Dirac field gravity shows analogies with the modified Brans–Dicke gravity, where each spinor term brings an effective gravity constant G divided by its field squared. The work shows that in order to obtain the classical minimum action principle and the general relativity limit of the macroscopic classical scale, quantum decoherence is necessary.
