in this study, a new efficient semi-analytical method is introduced to give approximate solutions of strongly nonlinear oscillators. the proposed method is based on combination of two different methods, the multi-step homotopy analysis method and spectral method, called the multi-step spectral homotopy analysis method (msham). in this method, firstly, we propose a new spectral homotopy analysis...

Objective: Chronic wounds have inadequate microvasculature (or blood vessels), resulting in poor healing. Both fresh human amniotic membrane (hAM) containing viable cells and devitalized hAM have been shown to stimulate angiogenesis in chronic wounds. However, the importance of retaining viable endogenous cells on the angiogenic activity of hAM remains unknown. To understand their role, we comp...

Objective: Human amniotic membrane (hAM) has been used to treat wounds for more than 100 years. However, widespread use of fresh hAM has been limited due to its short shelf life and safety concerns. To overcome these concerns, different preservation methods have been introduced. The majority of these methods result in devitalized hAM (dev-hAM). Recently, we developed a cryopreservation method t...

Objective: Regulation of oxidative stress and recruitment of key cell types are activities of human amniotic membrane (hAM) that contribute to its benefits for wound treatment. Progress in tissue preservation has led to commercialization of hAM. The majority of hAM products are devitalized with various degrees of matrix alteration. Data show the importance of hAM matrix preservation, but little...

HAIRY MERISTEM (HAM) proteins, members of the GRAS family of transcriptional regulators, are essential for maintenance of indeterminate growth in flowering plant shoots, loss-of-function ham mutants exhibiting a strikingly novel phenotype of shoot meristem arrest and differentiation. Specific cellular/molecular functions of HAM proteins underlying meristem maintenance are unknown. In this revie...

OBJECTIVE To develop a standardized validated version of the Hamilton Rating Scale for Depression (HAM-D) in Urdu. METHODS After translation of the HAM-D into the Urdu language following standard guidelines, the final Urdu version (HAM-D-U) was administered to 160 depressed outpatients. Inter-item correlation was assessed by calculating Cronbach alpha. Correlation between HAM-D-U scores at ba...

Human amniotic membrane-derived mesenchymal stem cells (hAM-MSCs) are capable of differentiating into several lineages and possess immunomodulatory properties. In this study, we investigated the soluble factor-mediated immunomodulatory effects of hAM-MSCs. Mitogen-induced peripheral blood mononuclear cell (PBMC) proliferation was suppressed by hAM-MSCs in a dose-dependent manner as well as hAM-...

PURPOSE Human amniotic membrane (HAM) transplantation is commonly used in corneal surface reconstruction and is known to inhibit neovascularization of this tissue. The purpose of the present study is to reveal the molecular basis underlying antiangiogenic activity of HAM. METHODS The effects of HAM protein on proliferation of vascular endothelial cells and corneal epithelial cells were determ...

The study provides original analytical data on the micronutrient profile of some traditional Italian hams, representative of the major ham categories produced in Italy: 4 dry-cured hams (Modena, Nazionale, Parma, San Daniele), 3 cooked hams (Cotto, Scelto, Alta Qualità), 1 smoked ham (Speck). Data on macronutrients (protein, lipid, moisture), energy, trace elements (Fe, Zn, Cu, Mn, Se), B vitam...
