Background: Since the ancient times, there has been awareness among people regarding the use of plants for the essential needs of a healthy and beautiful skin. Cosmetics are the products used to clean, beautify and promote attractive appearance. Cosmetics designed via incorporating natural sources such as herbs have been proven very fulfilling, in coping up with the present needs of different skin types. Objective: As due to increased pollution, allergy, microbes etc, human skin has become more sensitive and prone to faster aging. An attempt has been made to synthesize a pack ideal for all skin types. After the synthesis, all the parameters have been calculated in order to meet up the quality standards. Materials and Methods: The constituents were extracted from herbal ingredients such as Multani mitti, green tea, saffron, gram flour, turmeric, shwet chandan and milk powder. They were purchased from the local area and were dried separately, grinded, passed through sieve no 40, mixed homogenously and then evaluated for parameters including organoleptic, physicochemical, rheological features, phytochemical, stability, and irritancy examination. Results: The dried powders of combined pack showed good flow property which is suitable for a face pack. Organoleptic evaluation showed that the pack is smooth and pleasant smelling powder. Rheological findings justified the flow properties of the pack as it was found to be free flowing and non-sticky in nature. The results proved that the formulation was stable on all aspects. Irritancy test showed the negative. Stability tests performed revealed the inert nature of the pack. Conclusion: Thus, in the present work, we formulated a pack, which can be easily made with the easily available ingredients. It showed all the benefits of a face pack and further optimization studies are required on its various parameters to find its useful benefits on the human beings.

Abstract Blends of polycaprolactone (PCL) and poly(3-hydroxyoctanoate) P(3HO) were prepared by melt compounding. These immiscible blends exhibited droplet-matrix morphology at compositions up to 30 wt% P(3HO). Even though the addition of amorphous P(3HO) decreased the crystallinity of PCL, the crystallization temperature of the blends increased by 6 to 7 8C. Blends containing up to 30 wt% P(3HO) had higher crystallization rates, and lower crystallization half-times compared to neat PCL. The viscosity of PCL decreased upon addition of P(3HO), making the blends suitable for processing using a 3D bioplotter. Compositions with 10 to 30 wt% P(3HO) were ideal for processing, because of their improved crystallization kinetics, reduced stickiness and good flow properties. Estimation of the interfacial tension by fitting the Palierne model to the linear viscoelastic properties of the blends revealed good compatibility, which gave rise to synergistic effects in the thermal and mechanical properties. The fibres prepared by 3D bioplotting maintained droplet matrix morphology, with finer particle size than the original compounded material. In addition to favourable viscosity and thermal properties, the extruded fibres containing 30 wt% P(3HO) had comparable modulus to the neat PCL, while exhibiting good ductility. These blends may be suitable alternatives to PCL for biomedical applications, because they provide a range of crystallinities, crystallization rates and viscosities.

Fountain Of Youth

AbstractTransfusion (or drinking) of blood or of its components has been thought as a rejuvenation method since ancient times. Parabiosis, the procedure of joining two animals so that they share each others blood circulation, has revitalized the concept of blood as a putative drug. Since 2005, a number of papers have reported the anti-ageing effect of heterochronic parabiosis, which is joining an aged mouse to a young partner. The hallmark of aging is the decline of regenerative properties in most tissues, partially attributed to impaired function of stem and progenitor cells. In the parabiosis experiments, it was elegantly shown that factors derived from the young systemic environment are able to activate molecular signaling pathways in hepatic, muscle or neural stem cells of the old parabiont leading to increased tissue regeneration. Eventually, further studies have brought to identify some soluble factors in part responsible for these rejuvenating effects, including the chemokine CCL11, the growth differentiation factor 11, a member of the TGF-β superfamily, and oxytocin. The question about giving whole blood or specific factors in helping rejuvenation is open, as well as the mechanisms of action of these factors, deserving further studies to be translated into the life of (old) human beings.

This review attempts to portray the discovery and development of anticancer agents/drugs from diverse natural sources. Natural molecules from these natural sources including plants, microbes and marine organisms have been the basis of treatment of human diseases since the ancient times. Compounds derived from nature have been important sources of new drugs and also serve as templates for synthetic modification. Many successful anti-cancer drugs currently in use are naturally derived or their analogues and many more are under clinical trials. This review aims to highlight the invaluable role that natural products have played, and continue to play, in the discovery of anticancer agents.

It is one of focus topics that metro vibration affects foundations and environments. Assumed that crumb rubber mortar can be injected into foundations to form separate vibration layerbecause crumb rubber mortar is with better ductility and properties of vibration resistance,the layer decreases the effect of transportation load on foundation. Different diameters and volumes of rubber power were joined into the mortar to form rubber mortar by experiments. Then their flow degree and strenghth were measured and compared with ordinary mortar. The result shows that the rubber with smaller diameters can improve flow properties of mortar. When the volume inserting is ten percent of total sand volume, the flow property is best. The rubber mortar with best flow property was conserved for twenty-eight days. The damp property and impact resistant were determined under metro dynamic load. The experiment found that when the volume inserting is twenty percent of total volume, the damp value was improved twenty percent with twenty-five percent of absorbing energy and better separate vibration property. Therefore, the separate vibration layer can largely reduce the effect of vibration from metro and decrease the settlement of foundations of metro.

Abstract This essay examines some instances of interspecific dialogues between owls and human beings recorded in Nahuatl-language sources from the sixteenth century. Since ancient times, owls have been considered omens of death in Mexico. This article analyzes the cultural and linguistic context of this belief among the contact-period Nahuas: the import of tetzahuitl (omens) in the animistic worldview of the Aztecs, as well as the characteristic semantic pair in tecolotl, in chiquatli (“the owl, the barn owl”) to signify the lethal activities of the most representative messengers of the Lords of Death and Destiny, Mictlantecuhtli and Tezcatlipoca. Moreover, the essay shows how the ancient Nahuas considered the intelligibility of animal languages and engaged in active dialogues with the animal representatives of the gods, a form of communication that encompassed both the private and public spheres, as in these dialogues matters of disease, pollution, and warfare came into consideration.

Abstract The effects of the filler content and its surface treatment on the tensile and flow properties of the polypropylene (PP) composites filled with wollastonite (CaSiO3) were investigated. The results showed that the introduction of the filler could reinforce the PP resin, while the influence of the filler surface treatment on the tensile and flow property was insignificant. The melt volume flow rate (MVR) of the composites decreased nonlinearly, while the Young’s modulus increased nonlinearly with increasing filler weight fraction (ϕw); the tensile strength and tensile fracture strength increased significantly when ϕw was <10% and then decreased slightly with increasing ϕw. The elongation at break decreased significantly when ϕw was <10% and then decreased slightly with the increase of ϕw. Moreover, the Young’s modulus was estimated using the equation published earlier, and a good agreement was shown between the predicted data and the measured data.

Antiproliferative Activities

Juniper representatives are natural sources of plenty of bioactive metabolites and have been used since ancient times as folk remedies against tapeworms, warts, cancer, etc. The antiproliferative activities of junipers are attributed to podophyllotoxin (PPT), which is a precursor for the synthesis of efficient anticancer drugs. However, the natural sources of PPT, Sinopodophyllum hexandrum (Royle) T. S. Ying and Podophyllum peltatum L., are already endangered species because of their intensive industrial exploitation. Therefore, identification of other sources of PPT is necessary. This study is a broad comparative investigation of junipers, for which original sources have been accessed from different continents of the world. The present research is aimed at the identification of species, producing PPT and other lignans at concentrations that are sufficient for the high antiproliferative activity of the corresponding extracts. Cytotoxic juniper leaf extracts demonstrated a broad spectrum of activity on a panel of cancer cell lines. The antiproliferative properties of junipers were attributed to the combined activity of great diversity of lignans (podophyllotoxin, deoxypodophyllotoxin, β-peltatin, yatein, matairesinol, anhydropodorhizol, etc.), detected by UHPLC-HRMS and LC-ESI-MS/MS in the corresponding extracts. Several species of the genus Juniperus L. were outlined as perspective sources of drug precursors with potential pharmaceutical applications.

Since ancient times, man has attempted to express his inner feelings, covetousness and inclination to the world through various mediums e.g. poetry, drama, story, etc. Literature is one of the outcomes of the man’s efforts to reveal his aspirations to the world. Literature has avalanche of the widespread genre which is always subject to precisely apprehend and assimilate. Biography and autobiography are the two different genres of literature. The life of an individual is full of sweet and bitter experiences. There are incidences in an individual’s life which he or she never wants to share with anybody. Politicians, Rulers, Socialites, Movie Stars and other public personalities are also normal human beings. They too have their personal share of problems in their lives and in an attempt to resolve those issues they sometimes commit mistakes and even crimes which they never want anyone to know. Sometimes they commit these mistakes, misdemeanours, felonies or crimes because of their lustful desires or inclinations.  The present paper is a result of interest and curiosity to know if individuals share such information in their autobiographies.
