Abstract
The present investigation employs impulses and a non-local constraint to prove the existence are some various types of abstract differential and integrodifferential equations related to the Sobolev type. Semigroup theory, specifically variants of constant formula, is utilized to get the analytical results for those equations. Furthermore, findings using the Banach fixed point approach were examined using fuzzy numbers with values spanning the [Formula: see text] range, which includes the normal, convex, upper semi-continuous, and compactly supported interval. A description is given for each situation to illustrate the principle.

Abstract
The primary objective of postgraduate medical education is to produce specialists who provide highest quality of health care to suffering patients and return them to the community in the most functional capability. The secondary objective is to advance the cause of science through research and training. A postgraduate, after undergoing the required training in anaesthesiology, should be able to recognise the health needs of the community and apply cognitive and psychomotor skills to provide optimal anaesthetic care. Additionally, the anaesthesiologist should function as a perioperative physician being adept in perioperative care, pain medicine and critical care medicine. The 3-year postgraduate curriculum comprises experience in basic, subspeciality and advanced anaesthesia training. This structured training programme with a curriculum of increasing difficulty and learning incorporates ascending grades of difficulty, posing a challenge to the trainee's intellect and technical skills. Experience in basic anaesthesia training is aimed to lay stress on basic and fundamental aspects of anaesthetic management. Subspeciality anaesthesia training is needed to lay stress on the theory, special considerations and practice of subdisciplines of anaesthesiology. This document proposes a modular-structured, continuous, objectively evaluated, systematic training process that is monitored frequently and periodically, such that the trainee, at the end of training, is capable of appropriate anaesthetic management of disease conditions in a wide variety of situations.

Abstract
Photodeposition is a specific method for depositing metallic co-catalysts onto photocatalysts and was applied for immobilizing platinum nanoparticles onto cellulose, a photocatalytically inactive biopolymer. The obtained Pt@cellulose catalysts show narrow and well-dispersed nanoparticles with average sizes between 2 and 5 nm, whereby loading, size and distribution depend on the preparation conditions. The catalysts were investigated for the hydrogenation of para-nitrophenol via transfer hydrogenation using sodium borohydride as the hydrogen source, and the reaction rate constant was determined using the pseudo-first-order reaction rate law. The Pt@cellulose catalysts are catalytically active with rate constant values k from 0.09 × 10−3 to 0.43 × 10−3 min−1, which were higher than the rate constant of a commercial Pt@Al2O3 catalyst (k = 0.09 × 10−3 min−1). Additionally, the Pt@cellulose catalyst can be used for electrochemical hydrogenation of para-nitrophenol where the hydrogen is electrocatalytically formed. The electrochemical hydrogenation is faster compared to the transfer hydrogenation (k = 0.11 min−1). Modified cellulose (ModCe) was used in a photodeposition process as a support material for platinum nanoparticles. The supported catalysts were investigated for the transfer hydrogenation of para-nitrophenol (PNP) to para-aminophenol (PAP).![]()

Abstract
Rising concern about patient safety has resulted in growing interest in non-technical skills (NTS) among anaesthesiologists. Growing evidence suggesting the use of good NTS training in patient safety in simulated as well as real-world environment made them important in medical education. Both technical skills (TS) and NTS are interdependent. Successful task performance depends on effective integration of both TS and NTS for any given situation. Development of tools for assessing the NTS of an anaesthesiologist in improving health care outcomes is challenging. Teaching, understanding and evaluating NTS among anaesthesiologists in improving health care outcomes is a domain which is supposed to be a rich seam for future studies.

Abstract
The Green Lacewing Mallada desjardinsi (Navas) (Neuroptera: Chrysopidae) is the common chrysopid in tea plantations of the Anamallais (southern India). Guava trees dispersed in tea plantations accommodate a large population of this predator. Seasonality and intraguild predation of this chrysopid was investigated between December 2014 and November 2015. Spider eggs and spiderlings were important prey for this predator. Mallada desjardinsi preferred 22% eggs of Chrysso nigra, 20% of Neoscona mukerjei, 11% of Chrysso argyrodiformis and Cyrtarachne sp. and below 10% of the other spider species recorded. This is the first intraguild predation studies of M. desjardinsi on tea.

Abstract
Copper is the current interconnect metal of choice in integrated circuits. As interconnect dimensions decrease, the resistivity of copper increases dramatically because of electron scattering from surfaces, impurities, and grain boundaries (GBs) and threatens to stymie continued device scaling. Lacking direct measurements of individual scattering sources, understanding of the relative importance of these scattering mechanisms has largely relied on semiempirical modeling. Here we present the first ever attempt to measure and calculate individual GB resistances in copper nanowires with a one-to-one correspondence to the GB structure. Large resistance jumps are directly measured at the random GBs with a value far greater than at coincidence GBs and first-principles calculations. The high resistivity of the random GB appears to be intrinsic, arising from the scaling of electron mean free path with the size of the lattice relaxation region. The striking impact of random GB scattering adds vital information for understanding nanoscale conductors.

Abstract
We describe here an improved method of encapsulating doxorubicin in liposomes using phosphatidylcholine, cholesterol and synthetic tetramyristoyl cardiolipin. With this new composition of lipids the entrapment of doxorubicin was found to be > 90%. Cytotoxicity studies using vincristine-resistant HL-60/VCR leukaemia cells showed that liposome-encapsulated doxorubicin reverses multidrug resistance 5-fold compared with conventional doxorubicin and at levels equivalent to that obtained using liposomes with natural cardiolipin. In normal mice, liposome-encapsulated doxorubicin was much less toxic than the conventional drug. A dose of 25 mg kg-1 i.v. of conventional doxorubicin produced 100% mortality in mice by day 14, whereas liposomal doxorubicin exhibited only 10% mortality by day 60. Liposomal doxorubicin demonstrated enhanced anti-tumour activity against murine ascitic L1210 leukaemia compared with conventional doxorubicin. At a dose of 15 mg kg-1, liposomal doxorubicin increased the median life span with 12 of 18 long-term (60 days) survivors compared with only 3 of 18 with conventional drug. Mice injected i.v. with liposomal doxorubicin had plasma levels 44-fold higher than conventional doxorubicin, producing significantly higher (P < 0.02) area under the plasma concentration curve. An altered tissue distribution was also observed with liposomal doxorubicin; cardiac tissue demonstrating at least 2-fold lower levels with liposomal doxorubicin probably accounting for its lower toxicity. This altered pharmacokinetics of liposome-encapsulated doxorubicin, providing enhanced therapeutic advantage and the ability to modulate multidrug resistance, could be useful in a clinical setting.

Abstract
Epidermal growth factor (EGF), a potent mitogen produced primarily in the submandibular gland of adult male mice, has been implicated in modulating processes known to be of vital importance in the regulation of spermatogenesis. In the present investigation we demonstrate that submandibular gland EGF from adult male mice is indeed capable of displacing radiolabeled EGF from testicular membranes. Scatchard analysis of this binding site reveals that it is of high affinity (Kd = 0.77 nM) and low capacity (Bmax = 8.15 fmol/mg protein). Cross-linking of 125I-EGF to the identical membrane preparation resulted in the SDS-PAGE/autoradiography identification of a single band at approximately 170 kDa. Next, we examined the cellular distribution of the EGF receptor in the testis using biotin-streptavidin immunoperoxidase and employing different antisera probes generated to a conserved sequence of the EGF receptor. The Scatchard and cross-linking data described above, along with the immunocytochemistry results, suggest strongly that there is only one functional binding site for EGF in the adult testis and that this receptor is present in Sertoli and Leydig cells.

Abstract
Considerable evidence exists to suggest that epidermal growth factor (EGF) influences spermatogenesis directly. The tissue source of this EGF, however, is not yet clear. In this study we examine whether the testis itself can serve as a source of EGF. Gel filtration fractions of acid extracted testes exhibited the ability to displace 125I-EGF from testis membranes. The testicular fractions containing the 125I-EGF displacement activity coeluted within the same range as those of submandibular gland (SG) fractions containing mature EGF and prepared in an identical fashion. Next, we employed specific antisera probes to investigate first, whether the testis synthesizes this EGF displacement activity and second, to determine the cell distribution of the testicular EGF. Two types of antisera probes were employed: 1) commercially available antisera to mature EGF (EGFm), i.e. the 6,000 M(r) peptide, and 2) polypeptide specific antisera to the C-terminus of the EGF precursor (EGFp), i.e. the 140,000 M(r) integral membrane molecule which exhibits seven EGF-like repeats in addition to the EGFm. Metabolic labeling of testis with 35S-methionine was performed, followed by immunoprecipitation with the anti-EGFm antisera. Parallel studies using kidney and SG were used as positive controls. Fluorograms exhibited a prominent band at M(r) 140,000 for testis and kidney, corresponding to the EGFp. There was, in addition, a M(r) 50,000 band present for the testis. In SG, a band at M(r) 6,000, corresponding to EGFm, in addition to bands at M(r) 21,000 and 46,000 were observed also. Immunoblotting of testis, kidney, and SG membrane preparations with the specific antisera to either the EGFm or EGFp also resulted in identifying the EGFp at M(r) 140,000, as well as other lower mol wt bands. Preadsorption of anti-EGFm antisera with excess EGFm eliminated all of the specific bands that were immunoblotted. Peroxidase immunocytochemistry of testis, kidney, and SG was also performed using the specific antisera to either EGFm or EGFp. EGFp and EGFm staining in SG and kidney was identical to previously published results in which the distribution of EGFm in these tissues was established. In testis, EGFm immunostaining showed positive results in Sertoli cells, pachytene spermatocytes and round spermatids. In contrast, EGFp immunostaining was limited to pachytene spermatocytes and round spermatids. These results suggest that the testis must now be included in the list of tissues capable of synthesizing EGFp. Specifically, EGFp synthesis appears limited to the post meiotic germ cells.

Abstract
The presence of the epidermal growth factor receptor (EGFR) in testis, epididymis and vas deferens of monkeys was demonstrated using a polyclonal antibody (RK2) raised against a peptide-specific sequence of the intracellular domain of the human EGFR. Immunoblotting of membrane preparations revealed a specific band at approximately 170 kDa corresponding to those of controls, A431 and monkey liver cells. Cryostat sections were stained by biotin-streptavidin peroxidase immunocytochemistry. The liver showed positive staining along the basolateral membranes of the hepatocytes lining the sinusoids. The testis showed positive staining indicating the presence of EGFR in Leydig cells, Sertoli cells and peritubular cells. In the epididymis, immunostaining of the EGFR was observed on both the basolateral and the luminal borders of the epididymal epithelium. Immunofluorescence studies revealed a similar pattern of EGFR distribution in the epididymis and indicated that the luminal immunostaining was vesicular. In the vas deferens, positive immunostaining was detected in a pattern very similar to that observed in the epididymis. There was no positive staining in the interstitium of the epididymis or in the smooth muscle cell layers of the vas deferens. The sections of all tissues treated with pre-immune serum were negative. These results suggest that EGF in the primate testis may act at the level of somatic cells. In addition, the basolateral and luminal EGFR staining in the epididymis and vas deferens suggest that these cells respond to an EGF, or EGF-like, source both at the basal, luminal or at both sides of the cells, or that these tissues serve as sites of EGF transcytosis across the epithelium.
