ABSTRACT:
Weeds are spreading faster and creating serious problems throughout world with increasing population. Change in climate poses further
challenge for weed management. Weeds have major environmental, economic and social impacts; triggering damage to natural
agricultural lands, waterways, landscapes and coastal areas. The economic loss due to weeds is in thousand billions globally per
annum. Many measures and methods are in existence to manage the weeds and their effects. The early detection and eradication is the
prevention method and most effective means of weed control. Integrated weed management could be the damage control tool for
upcoming years.
Key words: Global face of weed, Invasive weed, impact of weed, economic loss, integrated weed management

ABSTRACT:
Low oral bioavailability of poorly water-soluble dosage form poses a great challenge during formulation development. Poor
water solubility and low dissolution rate are issues for the majority of upcoming and existing biologically active compounds.
Ziprasidone Hydrochloride (ZH) is BCS class-II drug having low solubility and high permeability. The aim of the present
investigation was to identify critical formulating and processing parameters which influences on quality of the
nanosuspension. Nanosuspension formulation of a poorly soluble drug was developed using nanoprecipitation-ultrasonication
technique. A total of 8 experiments were generated for screening 5 independent factors namely the amount of Ziprasidone
Hydrochloride (mg) (X1), amount of stabilizer (mg) (X2), solvent to anti-solvent volume ratio (X3), stirring speed (rpm) (X4)
and sonication time (min) (X5). Mean particle size (nm) (Y1) and Saturation solubility (µg/ml) (Y2) were selected as
dependent factors. The obtained results showed that nanosuspension prepared with the Poloxamer 407 has improved
saturation solubility as compare to all other stabilizers. Result also revealed that concentration of drug and stirring speed were
found to be promising formulating and processing parameters having prominent effect on quality of Ziprasidone Hydrochloride
nanosuspension.

ABSTRACT:
A simple, accurate and precise First Order Derivative, Induced Dual Wavelength and Dual Wavelength Methods are developed for the
simultaneous estimation of Trimetazidine hydrochloride (TMZ) and Metoprolol succinate (METO) in tablet dosage form. First Order
Derivative method was developed using two wavelengths which are 243.93 nm (ZCP of METO) was used for quantification of TMZ and
268.92 nm (ZCP of TMZ) was used for quantification of METO. Induced Dual Wavelength was developed for TMZ shows similar equality
factor (absorbance ratio=1.897) and difference absorbance at 270nm (?max of TMZ) and 254nm, while METO shows similar equality factor
(absorbance ratio=3.852) and difference absorbance at 274nm (?max of METO) and 254nm. Dual Wavelength was developed TMZ shows
similar absorbance at 280 and 260 nm for estimation of METO, while METO shows similar absorbance at 264.20 and 282.60 nm for
estimation of TMZ. The linearity was established for above method over the concentration range of 40-200?g/ml for TMZ and 54-270?g/ml
for METO with correlation coefficient R2 for First Order Derivative 0.9990 and 0.9996, for Induced Dual Wavelength 0.9995 and 0.9991 and
for Dual Wavelength 0.9998 and 0.9993 respectively. Water was used as a solvent.
The results of the analysis were analyzed and validated statistically and recovery studies were carried out as per ICH guidelines. It can be
used for routine analysis of two drugs in bulk as well as in pharmaceutical formulations.

ABSTRACT:
Aim & objective: To study the nephroprotective effect of coenzyme Q10 and pentoxifylline on cisplatin induced nephrotoxicity in
animals.The study would be beneficial to understand the effects of coenzyme Q10 and its combination with pentoxifylline on
experimentally induced nephrotoxicity in animals and to study the histopathology of kidney.
Material & Method: Nephrotoxicity was experimentally induced by cisplatin. Coenzyme Q10 (10mg/kg, i.p), pentoxifylline (45 mg/kg, i.p)
and its combination were evaluated for their nephroprotective effect in cisplatin induced nephrotoxic rats. Serum bio-chemicals parameters
like Creatinine, Albumin, Calcium, Magnesium and Uric acid were measured using enzymatic kits commercially available. Further
histopathologic studies were carried out.
Results: Coenzyme Q10 and pentoxifylline treated group showed significant decrease in serum creatinine, magnesium, calcium, uric acid
and albumin levels Histopathologic studies showed that rats treated with coenzyme Q10 and pentoxifylline individually retain minimal
inflammatory cellular infiltration and retain the tissue to normal structure, while combination of both coenzyme Q10 and Pentoxifylline
showed normal kidney tissue architecture.
Conclusion: coenzyme Q10 and pentoxifylline has a nephroprotective effect that was proven by biochemical and histopathological
analysis. Coenzyme Q10 and pentoxifylline has been shown nephroprotective activity with greater protective action as compare to alone
dose treatment.

ABSTRACT:
The unwanted unintentionally propagated plant species with crops, called as weeds may have inhibitory effect on
bothersome weeds. Part of plant as whole or their extract or their metabolite can be used as Allelopathic plant.
Although any of these parts have which kind of effect on any selected plant; is matter of study. In current study such
phenomenon has been explained in brief. The study shows that almost every plant has some allelopathic effect by
any way on any other plant. The mechanism of action may be Volatilization, Leaching, Root exudation,
Decomposition and act as herbicide for other plant.

ABSTRACT:
Liquisolid technique is a novel approach for the concept of dosage formulation to improve the bioavailability, dissolution rates and
rapid disintegration of water insoluble drugs via oral route of administration. In this technique of formulation involves drugs
dissolved in suitable non-volatile liquid vehicles, and converted in to powdered forms of liquid medications compact, they are
compressible and acceptably industrial applicable by combination with selective powder excipients. The liquisolid technique
allows the formulation transformation into solid drug delivery systems. With this technique as compare to commercial
conventional tablet it shows confirmed increasing dissolution rates in addition to improved bioavailability. Approach has been
successfully applied for poorly soluble drugs in release of low dose enhancement. However, for the high dose drugs one of the
limitations for the formulation because of more liquid/vehicle required for the drug dissolution procedure as well high amounts of
carrier and coating material are required in due course foremost to an unacceptably high tablet weight.

ABSTRACT:
Combination therapies are widely used to treat cardiovascular and diabetic patients. Current study is designed to develop fixed dose
combination of anti diabetic and anti hypertensive drugs to treat hypertension in patients suffering from diabetics. Fixed dose combination was
designed as bilayer tablets with immediate release and sustained release layers. Immediate release was loaded with drugs that required for
immediate action by achieving blood level immediately and sustained release layer to maintain the drug concentration throughout the time as
designed. Antidiabetic drug Alogliptin Benzoate and antihypertensive drug Valsartan were incorporated in immediate release layer to show
immediate action whereas Metformin HCl was loaded as sustained release layer to maintain the drug level throughout the targeted time period.
Immediate release layer was manufactured using direct mixing process with optimized disintegrant concentration for faster release. Sustained
release layer of Metformin HCl was manufactured employing wet granulation approach using HPMC and POLYOX resin as release control
polymer in combination. Formulation was optimized using statistical designed. Physico-chemical parameters like weight variation, hardness,
friability and in-vitro dissolution of bilayer tablets were evaluated..
