Fertility preservation following pediatric cancer therapy programs has become a major avenue of infertility research. In vitro spermatogenesis (IVS) aims to generate sperm from banked prepubertal testicular tissues in a lab setting using specialized culture conditions. While successful using rodent tissues, progress with human tissues is limited by...

Coherence narrowing and collision broadening of the 5s5p1P1 level of strontium have been studied. The natural lifetime of this level has been determined to be 4.68 ± 0.10 ns. The oscillator strength of the 4607 Å transition is 1.94 ± 0.06, and the f values of the transitions from the 5s6p, 5s7p, and 5s8p1P1 levels to the ground level and the 5s4d1D...

The lifetime of the 5p2P3/2 level of Sr+ has been measured using the zero field level crossing (Hanle effect) technique with optical excitation from the ground state of the ion. The ions are produced in a discharge at the mouth of a furnace used to produce a strontium beam. No foreign gas is used to carry the discharge. An alignment depolarization...

The lifetime of the 5p2P1/2 level of Sr+ has been measured using the Hanle effect, or zero field level crossing technique, with optical excitation from the ground state of the ion. Circularly polarized light is used in the excitation and analysis. The ions are produced in a discharge at the mouth of the furnace used to produce a beam of strontium a...

While the reaction of Pya...

The reaction of 2-(3′-pyridylazo)imidazole (3′-PyaiH) or its 1-alkyl derivative, 3′-PyaiR, with Ru(CO)3(PPh3)2 has synthesized air stable, moisture insensitive, diamagnetic Ru(0) complexes, [Ru(CO)(3′-PyaiR)(PPh3)2]. The ligands serve as an unsymmetric N,N′-chelating agent (N(imidazole) and N(azo) are abbreviated as N and N′, respectively). The X-r...

The structure of [Os(phen)(ClaaiEt...

Pyridine and imidazole are connected by an azo group (NN) to synthesize 2-[(3′-pyridyl)azo]imidazole (3′-PyaiH) and this has been confirmed by X-ray structure determination. The N(1)-alkylation gives 1-alkyl-2-[(3′-pyridyl)azo]imidazole (3′-PyaiR′) (R′=Me (2a), Et (2b), Bz (2c)). The reaction between Mn(ClO4)2·6H2O and 3′-PyaiR′ in methanol has syn...

[Mn(RaaiR′)4](ClO4)2 complexes have been synthesised by reacting Mn(ClO4)2·6H2O and RaaiR′ in methanol (RaaiR′ = 1-alkyl-2-arylazo)imidazole, R = H (a), Me (b), Cl (c); R′ = Me (1), Et (2)). The orange–red crystalline compounds were characterised by microanalytical, spectroscopic, magnetic, thermal and electrochemical data. A single-crystal X-ray d...

Imidazolyl and 3′-pyridyl are linked by azo bond (–NN–) to synthesize hitherto unknown mixed heterocyclic azo molecules, 2-[(3′-pyridyl)azo]imidazole (3′-PyaiH). Alkylation in presence of NaH has synthesized 1-alkyl-2-[(3′-pyridyl)azo]imidazole (3′-PyaiR′). 3′-PyaiR′ include three types of N-donor centers: N(imidazole), N(azo) and a peripheral N(p...

Solasodine (C27H42O2N), a nitrogen analogue of diosgenin reduced serum cholesterol and LDL cholesterol by 73.3% and 73.5% and prevented atherogenesis (Atherogenic index-control: 1.99; athero- group: 3.12; solasodine treatment 2.12–2.32).

Agglutination and immobilization tests were performed to detect the presence of sperm antibodies in the sera of 100 vasectomized men. Overall, 52% of subjects had sperm antibodies. 50% showed agglutinating antibodies, while immobilizing antibodies were present in 40%. Of the 52 positive cases, 23 showed agglutinating antibody alone in their sera. 7...

Metronidazole, in a single dose of 2 g for 2 days, was given to 73 patients with non dysenteric amoebic colitis 48 of whom were symptomatic and 25 asymptomatic. Three stool samples of the patient were examined after one, 2 and 3 mth of treatment. Results were assessed on clearance of the stools with cysts of Entamoeba histolytica. 41 of the 43 pati...

Fresh stools were examined for...

The stools of 50 patients with nondysenteric amebic colitis positive for cysts of E. histolytica were tested on 21 occasions over the course of 35 days, with a view to finding how many times stools should be tested to detect the maximal number of patients excreting cysts of E. histolytica. It was found that a single stool examination will detect 44...
