Many antiepileptic drugs (AEDs) are extended-release (ER) tablets, such that an entire day’s dose is taken only once or twice daily. A patient taking four levetiracetam ER 500 mg tablets twice daily was alarmed when, after switching from a generic manufactured by Sun to a generic manufactured by Lupin, ER tablet remnants appeared as intact tablets in his stool, suggesting no drug was absorbed. ...

in this study, attempts were made to evaluate the effect of various acrylic acid based carbopols on the release profile of a beta-adrenoreceptor blocking drug, propranolol hcl, from matrix-type tablets invitro. for this purpose, tablets containing 160 mg of propranolol hcl along with various amounts of carbopols 934 (c934), 971 (c971), 974 (c974) and pemulen (pem) were prepared using the wet gr...

This preliminary research was aimed at finding the roots in various Eurasian proto-languages directly related to pulses and giving the words denoting the same in modern European languages. Six Proto-Indo-European roots were indentified, namely arnk(')- ('a leguminous plant'), *bhabh- ('field bean'), *[Formula: see text] ('a kernel of leguminous plant', 'pea'), ghArs- ('a leguminous plant'), *ke...

The transforming (onc) genes of oncogenic retroviruses share most or all of their coding sequences with normal cellular genes termed proto-onc genes. The viral genes differ from proto-onc genes in virus-specific promoters and in various point mutations and substitutions of cell-derived coding regions. In view of the structural similarities between viral oncogenes and cellular proto-onc genes, t...

The oncogene hypothesis postulates that mutated cellular genes, termed proto-onc genes, function as cancer genes because they are related to retroviral onc genes. However, in contrast to retroviral onc genes, mutated proto-onc genes from cancers are not sufficient for carcinogenesis. Therefore, it has been proposed that mutated proto-onc genes depend on other proto-onc genes for carcinogenesis....

The relationship between Mg-protoporphyrin IX (Mg-Proto IX) signals and plant's tolerance to cold stress is investigated. Arabidopsis seedlings grown for 3 weeks were pretreated with 2 mM glutamate (Glu) and 2 mM MgCl2 for 48 h at room temperature to induce Mg-Proto IX accumulation. Then cold stress was performed at 4°C for additional 72 h. Glu + MgCl2 pre-treatments alleviated the subsequent c...

MeduIIary thyroid carcinoma (MTC) occurs both sporadically and in the autosomal dominantly inherited multiple endocrine neoplasia (MEN) type 2 syndromes. The distinction between true sporadic MTC and a new mutation familial case is important for future clinical management of both the patient and family. The susceptibility gene for hereditary MTC is the RET proto-oncogene. DNA analysis for g...

It is often claimed that Kripke (1980) and Putnam (1975) established that many predicates, most importantly natural kind predicates, are like proper names in being rigid designators. This insight is generally regarded as having important consequences in the theory of necessary truths: the rigidity of terms such as 'Hesperus', 'Phosphorus', 'water' and 'H 2 O' is used in explaining why identity ...
