Staphylococcus aureus is an increasing problem in clinical practice because of reduced susceptibility to available antibiotics. The objective of the study was to determine the frequency of Methicillin-resistant S. aureus (MRSA) in Peshawar, Pakistan. Clinical isolates of S. aureus were subjected to determination of antibiotic resistance, MICs and inducible(More)
Three new triorganotin(IV) dithiocarboxylates (1-3) with general formula R(3)SnL, where R=C(4)H(9) (1), C(6)H(11) (2), C(6)H(5) (3) and L=4-(4-nitrophenyl)piperazine-1-carbodithioate, have been synthesized and characterized by elemental analysis, Raman, FT-IR, multinuclear NMR ((1)H, (13)C and (119)Sn) and mass spectrometry. The crystal structure of complex(More)

This study was conducted to isolate antagonistic and biotechnologically potent bacteria from environment. Micrococcus luteus was the only bacterium found producing antimicrobial metabolites and exhibited good probiotic characteristics. Micrococcus luteus showed antibacterial activity against foodborne pathogens, Salmonella typhimurium (16-20 mm), Listeria(More)
Tuberculosis is a global health problem, and its early diagnosis is the ultimate strategy for prevention and control. The current study was undertaken to evaluate conventional and molecular diagnostic assays for the detection of mycobacteria in pulmonary tuberculosis (TB) patients from Khyber Pakhtunkhwa region of Pakistan. A total of 259 clinically(More)
In this study, soil bacteria were isolated and characterized including its antimicrobial peptide. For this, soil samples were collected from agriculture lands. Soil samples were diluted and cultured in nutrient agar plates to obtain the isolated bacterial colonies. Antimicrobial peptide producers were screened by stab overlay, agar well diffusion, cross(More)
New zinc(II) carboxylate complexes [Zn(3-F-C6H4CH2COO)2]n (1), [Zn3(3-F-C6H4CH2COO)6(Phen)2] (2) and [Zn3(3-F-C6H4CH2COO)6(bipy)2] (3) were synthesized and characterized by atomic absorption, single crystal structural analysis and IR studies. Complex 1 crystallizes as a coordination polymer constituting a web of μ-η1,η1 carboxylate bridged tetrahedral zinc(More)
This paper presents a high-gain cavity resonant antenna (CRA), consisting of an FSS layer placed above an aperture coupled microstrip patch antenna (ACMPA). Geometry of the proposed FSS superstrate is highly reflective with |Γ > 0.9|. Ray-tracing method has been employed for determining the resonant condition of the antenna. ACMPA operating at S-band is(More)
Plants face changes in leaves under lead (Pb) toxicity. Reduced glutathione (GSH) has several functions in plant metabolism, but its role in alleviating Pb toxicity in cotton leaves is still unknown. In the present study, cotton seedlings (28 days old) were exposed to 500 μM Pb and 50 μM GSH, both alone and in combination, for a period of 10 days, in the(More)
This paper presents modified Sierpinski monopole fractal antenna for dual band applications. Considerable size reduction upto 53.5% in terms of the overall size of the antenna and 74.24% in terms of the copper remaining is achieved in comparison to the conventional triangular monopole antenna. The fractalization is done upto second order for radiation of(More)
