A simple synthesis of highly planar extended π-electron molecules is particular interest for the development efficient nonfullerene acceptors in organic solar cells with high light absorption and mobility. Herein, two small-molecule (MPU7 MPU8) a diketopyrrolopyrrole core connected to CPTCN end-capping groups (A2) via thienylethynylselenophene (MPU7) or thienylethynylthiophene (MPU8) linkers ar...

This study examines preferences for specific contraceptive methods and factors related to method choice (age, parity, residence, knowledge, and interpersonal communication) in Pakistan. Data were obtained from the 1993 Choice of Contraceptive Methods and Drop Outs in Family Planning survey in the Punjab and the NWFP. The sample included interviews with 375 out of 1929 family planning acceptor...

Information on the biosynthesis of the D-arabinans of the cell wall of Mycobacterium tuberculosis is rapidly emerging, with the promise of new targets for drug development against tuberculosis. Accordingly, arabinosyl transferase assays were developed utilizing synthesized [1-14C]-beta-D-arabinofuranosyl-1-monophosphoryldecaprenol as donor and a variety of O- and S-alkyl arabinosides as accepto...

The labeling patterns produced by radioiodinated botulinum neurotoxin (125I-BoNT) types A and B at the vertebrate neuromuscular junction were investigated using electron microscopic autoradiography. The data obtained allow the following conclusions to be made. 125I-BoNT type A, applied in vivo or in vitro to mouse diaphragm or frog cutaneous pectoris muscle, interacts saturably with the motor n...

This paper estimates the number of births averted in Pakistan by analyzing the statistics of the Population Planning Programme (PPP), relevant data from the National Impact Survey (NIS) of the 1968, and the Pakistan Fertility Survey (PFS) of 1975. In 1975-76 1392 million units of conventional contraceptives (pills, IUDs, and sterilization) were distributed. Couple-years of protection are cons...

A new family of molecule-based magnets related to the V[PTCE]x · yCH2Cl2 magnet (PTCE = phenyltricyanoethylene, x = ~2, y = ~0.2) was synthesized utilizing new reversible oneelectron acceptors with the general form MexPTCE (PTCE = phenyltricyanoethylene, x is the number of methyl groups on the phenyl ring, Me = -CH3). These new acceptors were synthesized for the purpose of studying electronic a...

Fructophilic lactic acid bacteria (FLAB) are strongly associated with the gastrointestinal tracts (GITs) of Apis mellifera L. worker bees due to the consumption of fructose as a major carbohydrate. Seventy-seven presumptive lactic acid bacteria (LAB) were isolated from GITs of healthy A. mellifera L. adults, which were collected from 5 different geographical locations of the Apulia region of It...

The Benzylideneacetones as part of a broad group of compounds, some of them of natural origin and found in several plant species [1], are of great interest in pharmaceutical and polymers areas [2, 3]. Also, these compounds have optical properties of interest in photonics [4,5]. Recently, it has been demostrated that 1,3-diketonate ligands in complex compounds with lanthanide ions, containing gr...
