Progressive supranuclear palsy (PSP) is a rare neurodegenerative parkinsonian syndrome with distinct clinical features which tends to be progressive, causing vertical supranuclear gaze palsy, frontal lobe cognitive decline, postural instability and progressive axial rigidity. Clinical examination typically reveals ocular motor dysfunction including restricted vertical gaze, slow vertical saccades and “eyelid opening apraxia” with intact vestibule ocular reflex. PSP falls under the rubric of Parkinsonism plus syndromes that are a group of heterogeneous degenerative neurological disorders that differ from the classical idiopathic Parkinson’s disease. PSP is often underreported, making it important for clinicians to be aware of this disorder. Here we report a case of PSP, which presented primarily with speech disturbances and recurrent falls due to postural instability. On investigating, the magnetic resonance imaging (MRI) revealed a classical sign diagnostic of PSP. This teaching case report describes management and prognosis of the disease

Conveying nanopowder or nanoparticles are involved in the numerous industry fields, but discontinuous and unstable transportation often takes place, and even the pipes clogged because of nanoparticle aggregation. Understanding in detailed the microscopic characteristics of nanoparticles suspended in the base fluid will play a vital role.

In this paper, a mathematical five-dimensional dynamical system involving an SVEIR model of infectious disease transmission in a chemostat is proposed. A profound qualitative analysis is given. The analysis of the local and global stability of equilibrium points is carried out. It is proved that if R>1, then the disease-persistence (endemic) equilibrium is globally asymptotically stable. However, if 1≤R, then the disease-free equilibrium is globally asymptotically stable in R5.

Bone healing is a complex process consisting of multiple sequential phases needing the coordinated interaction of various cells, growth factors, cytokines and mechanical conditions. However, bone healing is one of the rare regenerative processes resulting in complete restoration of form and function. Fracture treatment aims towards a swift return to functional use of the injured limb. Therefore stabilization is a key requisite. In the veterinary clinic difficult fracture cases often require a unique stabilization by custom made external fixation. While this fixation technique harbors risk factors it offers a high flexibility essentially needed to successfully treat small animal fracture patients. Here we draw the connection between the up-to-date knowledge in bone healing and case reports of external fixation techniques from the small animal practice with respect to benefits and risk factors.

Human islet amyloid polypeptide (hIAPP), a 37 residue peptide hormone is an ingenious factor in pancreatic amyloid deposits found in cases with type-2 diabetes. Its aggregation into small toxic oligomeric species is presumed to be the reason for cells debilitation and demise in case of diabetic patients.

The aim of this manuscript is to study cyclodextrins (CDs) as a potential excipient to suppress bitterness and enhance palatability of pediatric liquid preparations for Cetirizine, an extremely bitter drug. Natural α, β and γ CDs; and β CD derivatives such as hydroxyl propyl (HP), randomly methylated (RM) and sulfobutyl ether (SBE) β-CDs were screened in different molar ratios of 1:1, 1:2 and 1:3 for their inhibition of the extremely bitter taste of Cetirizine using the human gustatory sensation test.

Capsaicin, an active ingredient of Capsicum fruit, is currently undergoing “revival” in the clinical management of pain. However, the choice of its formulation is rather limited to the use of “old-fashioned” tinctures and recently the patches. In an attempt to improve the therapeutic outcome and develop its skin-friendly formulation, we prepared the vesicle-based drug delivery system with capsaicin.

A reliable, fast, sensitive and selective Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry (UPLC-MS/MS) method has been developed and validated for the determination of fenofibrate in marketed product (Lipanthyl) and human plasma. The chromatographic separation was performed on a reversed-phase Acquity®BEH C18 column (1.7 μm particle size, 50 mm x 2.1 mm ID) with an isocratic elution profile and mobile phase consisting of methanol and water (80:20, %, v/v). To achieve optimum chromatographic condition the influence of mobile phase composition and flow rate was investigated. The total chromatographic analysis time was as short as 2 min.
