the main objective of the present study was to formulate gastroretentive effervescent sustained release drug delivery systems of risperidone floating tablets with the help of methocel® k15, ethocel® standard 7fp premium, eudragit ® rs100 sustained release polymers to improve its safety profile, bioavailability and patient compliance. risperidone floating tablets were formulated by wet granulati...

In mice, in utero exposure to 2,3,7,8-tetrachlorodibenzo-p- dioxin (TCDD) reduces the number of dorsolateral prostatic buds resulting in a smaller dorsolateral prostate and prevents formation of ventral buds culminating in ventral prostate agenesis. The genes and signaling pathways affected by TCDD that are responsible for disrupting prostate development are largely unknown. Here we show that t...

Secreted R-spondin proteins (RSPOs1–4) function as adult stem cell growth factors by potentiating Wnt signaling. Simultaneous binding of distinct regions of the RSPO Fu1–Fu2 domainmodule to the extracellular domains (ECDs) of the LGR4 G protein–coupled receptor and the ZNRF3 transmembrane E3 ubiquitin ligase regulates Wnt receptor availability. Here, we examine the molecular basis for the diffe...

Abstract This paper investigates the factors that influence adoption of RSPO and Thai-GAP certification by oil palm smallholder farmers in Thailand. A random sample 77 certified, 108 non-certified RSPO, 87 67 were interviewed to investigate explaining scheme adoption, respectively. The logit model was used analyse relationships between decision-making farmers. results show membership farmer gro...

Abstract Smallholders are a substantial part of the oil palm sector and thus key to achieving more sustainable production. However, so far their yields remain below potential. The Roundtable on Sustainable Oil Palm (RSPO) aims include smallholders in sustainability certification strengthen rural livelihoods reduce negative environmental impacts. This study determine if how certified perform dif...

abstract: background: a new type of drug delivery system known as mucoadhesive film has been developed for oral thrush treatment. due to comfortable use of this drug delivery system, this would be encouragingly utilized, especially in babies and patient under chemotherapy. nystatin mucoadhesive film (nmf) is a polymeric film which is adhered to front upper gum and back to the upper lip and rele...

the most frequent adverse effects of indomethacin like other nsaids are gastro–intestinal and central nervous system disturbances. extended release or enteric release formulations minimize these symptoms. the objective of this study was to develop an extended release pellet formulation of indomethacin by the centrifugation (rotary fluid bed granulation) or powder layering method. layered, nonpa...

the influence of various polymers on the release rate of lithium carbonate from matrix-type tablets was investigated in an attempt to formulate a sustained release solid dosage form. for this purpose, tablets containing 450 mg of lithium carbonate along with various amounts of carbopol 934p, 971p, 974p, pemulen and eudragit rlpo as retarding agents and inactive ingredients (e.g. pvp, avicel or ...

ibuprofen solid dispersions were prepared by the solvent and fusion-solvent methods using polyethylene glycol (peg), polyvinylpyrrolidone (pvp), eudragit rs po, eudragit rl po and hydroxypropylmethylcellulose (hpmc) as carriers to improve physicochemical characteristics of ibuprofen. the prepared solid dispersions were evaluated for the flowability, solubility characteristics and dissolution be...
