Synthesis, Biological, Spectral, and Thermal Investigations of Cobalt(II) and Nickel(II) Complexes of N-Isonicotinamido -2′,4′-Dichlorobenzalaldimine

A new series of 12 complexes of cobalt(II) and nickel(II) with N-isonicotinamido-2′,4′-dichlorobenzalaldimine (INH-DCB) with the general composition MX(2) · n(INH-DCB) [M = Co(II) or Ni(II), X = Cl(−) ,Br(−), NO(3)(−), NCS(−), or CH(3)COO(−), n = 2; X = ClO(4) (−), n = 3] have been synthesized. The nature of bonding and the stereochemistry of the complexes have been deduced from elemental analyses, infrared, electronic spectra, magnetic susceptibility, and conductivity measurements. An octahedral geometry has been suggested for all the complexes. The metal complexes were screened for their antifungal and antibacterial activities on different species of pathogenic fungi and bacteria and their biopotency has been discussed

Synthesis, Spectral, and Biological Properties of Copper(II) Complexes of Thiosemicarbazones of Schiff Bases Derived from 4-Aminoantipyrine and Aromatic Aldehydes

We have synthesized a novel series of Schiff bases by condensation of 4-aminoantipyrine and various aromatic aldehydes followed by reaction with thiosemicarbazide. These thiosemicarbazones are potential ligands toward transition metal ions. The reaction of copper(II) salts with 4[N-(benzalidene)amino]antipyrinethiosemicarbazone (BAAPTS), 4[N-(4′-methoxybenzalidene) amino] antipyrinethiosemicarbozone (MBAAPTS), 4[N-(4′-dimethylamino benzalidene) amino] antipyrinethiosemicarbazone (DABAAPTS), and 4[N-(cinnamalidene) amino] antipyrinethiosemicarbazone (CAAPTS) resulted in the formation of solid complexes with the general composition CuX(2) · (H(2)O)(L)(X = Cl, Br,NO(3),NCS, or CH(3)COO; L = BAAPTS, MBAAPTS, DABAAPTS, or CAAPTS). These complexes were characterized through elemental analysis, molecular weight, electrical conductance, infrared, electronic spectra, and magnetic susceptibilities at room temperature. Copper(II) complexes with BAAPTS and MBAAPTS were screened for antibacterial and antifungal properties and have exhibited potential activity. Thermal stabilities of two representative complexes were also investigated

Aux-Drop: Handling Haphazard Inputs in Online Learning Using Auxiliary Dropouts

Many real-world applications based on online learning produce streaming data that is haphazard in nature, i.e., contains missing features, features becoming obsolete in time, the appearance of new features at later points in time and a lack of clarity on the total number of input features. These challenges make it hard to build a learnable system for such applications, and almost no work exists in deep learning that addresses this issue. In this paper, we present Aux-Drop, an auxiliary dropout regularization strategy for online learning that handles the haphazard input features in an effective manner. Aux-Drop adapts the conventional dropout regularization scheme for the haphazard input feature space ensuring that the final output is minimally impacted by the chaotic appearance of such features. It helps to prevent the co-adaptation of especially the auxiliary and base features, as well as reduces the strong dependence of the output on any of the auxiliary inputs of the model. This helps in better learning for scenarios where certain features disappear in time or when new features are to be modelled. The efficacy of Aux-Drop has been demonstrated through extensive numerical experiments on SOTA benchmarking datasets that include Italy Power Demand, HIGGS, SUSY and multiple UCI datasets.

Amebic Liver Abscess With Intra-Biliary Rupture

The case of a large amebic liver abscess with an atypical presentation is reported. High output bile drainage persisted after ultrasound guided percutaneous catheter drainage because of a preexisting communication of the abscess with the right hepatic ductal system. The abscess was managed successfully by surgical evacuation and internal drainage into a defunctioned jejunal loop

New and improved method of bamboo cultivation in semi arid areas of Indian Thar desert

Bamboo (Dendrocalamus strictus Roxb.) is widely utilized in construction, pulp and paper, furniture, food and medicine, fuel and handicrafts for a long time. Due to its wider application, a field experiment was carried out to check its cultivation requirements besides its success rate in semi arid area of Indian Thar desert. In the present work, Guggul (Commiphora wightii Arnott.) which is a resident plant of Thar desert has been proved as a potential intercrop in bamboo cultivation. Improved growth was observed in bamboo with plant height (8.92 to 20.74 feet), number of culms (19 to 38), culm diameter (2.2 to 4.3 cm) during intercropping of guggul. Among different methods of irrigation, highest growth was recorded in drip irrigated plants where 50% recommended N:P:K and organic manure were given in combination followed by N:P:K sole. This study indicates that Guggul may play a role in microclimate development in the bamboo cultivation. This is the first report on successful bamboo cultivation in semi arid area of desert using an intercrop.Key words: Dendrocalamus, soil enzymes, fertilization, guggul, nitrogen

Limb splinting for intravenous cannulae in neonates: A randomised controlled trial

Objective: To evaluate the efficacy of peripheral intravenous (IV) cannula site joint immobilisation by splint application on functional duration of peripheral IV cannula in neonates. Design: Randomised controlled trial. Setting: Neonatal intensive care unit of a tertiary care hospital. Participants: Neonates requiring continuous IV infusion for an expected duration of more than or equal to 72 hours. Intervention: Eligible cannulations were randomised to either “splint” or “no-splint” group. In the splint group, a cardboard splint was used to immobilise the joint at peripheral IV cannula site. No attempt was made to immobilise the limb in the no-splint group. Outcome measure: Functional duration of a peripheral IV cannula measured as interval from time of insertion to the development of predefined sign of removal (extravasation, blockage, inflammation). Results: A total of 69 peripheral IV cannulations in 54 neonates were randomised to either the splint (n = 33) or no-splint group (n = 36). Both groups were comparable in birth weight, gestation, site of cannulation and nature of fluids administered. Mean functional duration of cannula was lesser in the splint group compared to the no-splint group (h; 23.5 (SD15.9) vs 26.9 (SD15.5), mean difference: −3.3 h, 95% CI −11.02 to 4.3 h) although the difference was not statistically significant (p = 0.38). Extravasation at cannula site was found be the commonest indication for cannula removal in both the groups (84% vs 76.5%). Conclusion: Joint immobilisation with splint at cannula site did not improve the functional duration of peripheral IV cannula

Comparison of newly optimized Moses technology vs standard holmium: YAG for endoscopic laser enucleation of the prostate

Introduction: The purpose of this study was to describe our initial experience of using a newly optimized Moses technology that is part of the second-generation Moses platform specifically designed for holmium laser enucleation of the prostate (M2-HoLEP) and compare it with patients undergoing HoLEP using standard holmium:YAG technology (S-HoLEP). Materials and Methods: We retrospectively collected data on patients who underwent M2-HoLEP and compared it with the last 50 patients in whom we performed S-HoLEP. Specifically, we compared preoperative symptom scores for lower urinary tract symptoms (LUTS) and erectile dysfunction (ED), preoperative objective voiding metrics, as well as intraoperative characteristics, perioperative characteristics, postoperative complications, postoperative symptom scores for LUTS and ED, and postoperative objective voiding metrics. Additionally, we evaluated the ability for same-day discharge following surgery in the M2-HoLEP group. Results: We included 104 total patients for analysis. We compared the first 54 patients undergoing M2-HoLEP with 50 patients undergoing S-HoLEP. Both groups had similar age, body mass index, use of anticoagulation medication, LUTS and ED scores, and objective voiding metrics. Operations performed with M2-HoLEP had faster mean hemostasis time (8.7 vs 10.6 ± 6 minutes, p = 0.03) as well as hemostasis rate (0.13 vs 0.30 min/g, p = 0.01). Same-day discharge was achieved in 69.4% of patients in the M2-HoLEP group. Postoperatively, both groups also had similar and low rates of urinary retention and complications. At follow-up, both groups had similar symptom scores for LUTS and ED, as well as similar objective voiding metrics. Conclusions: The newly optimized Moses pulse modulation technology is safe and efficient for the treatment of benign prostate hyperplasia. Such technologic improvements in the laser have greatly enhanced the feasibility of same-day discharge of patients undergoing HoLEP

Effect of dietary supplementation of crude microalgal extracts on growth performance, survival and disease resistance of Lates calcarifer (Bloch, 1790) larvae

The present study aimed to assess growth performance and health status of Lates calcarifer larvae fed with crude microalgal extracts. Larvae weighing 5.96 ± 0.39 mg were randomly divided into four experimental groups in triplicates, with each replicate having 35 larvae. Four diets formulated to contain 55% protein and 12% lipid, were prepared with pigment rich microalgal extracts at 0% (T1) and 1% each of crude phycocyanin (T2), chlorophyll (T3) and astaxanthin (T4) extracts. The experiment was carried out in 30 l plastic tanks by feeding experimental diets to satiation. There was no significant difference (p<0.05) in growth performance in larval groups fed different experimental diets. Percentage survival during the feeding experiment was significantly higher in the astaxanthin fed group (77.14±1.65) and lower in chlorophyll fed group (36.19±0.95) compared to control group. Cannibalism (%) was significantly reduced in the treatments fed astaxanthin (7.61±0.95) and phycocyanin (8.57±0.3) pigmented diets compared to chlorophyll fed group (13.33±0.95) and control group. Bacterial challenge with pathogenic Vibrio alginolyticus revealed highest resistance in astaxanthin and phycocyanin fed larvae. The study confirms that astaxanthin and phycocyanin at 1% dietary levels improve survival and disease resistance in Asian seabass larvae but do not affect growth performance
