Potential Anticancer Properties of Osthol: A Comprehensive Mechanistic Review.

Cancer is caused by uncontrolled cell proliferation which has the potential to occur in different tissues and spread into surrounding and distant tissues. Despite the current advances in the field of anticancer agents, rapidly developing resistance against different chemotherapeutic drugs and significantly higher off-target effects cause millions of deaths every year. Osthol is a natural coumarin isolated from Apiaceaous plants which has demonstrated several pharmacological effects, such as antineoplastic, anti-inflammatory and antioxidant properties.

WHATCH'EM: A Weather-Driven Energy Balance Model for Determining Water Height and Temperature in Container Habitats for .

The mosquito virus vector () exploits a wide range of containers as sites for egg laying and development of the immature life stages, yet the approaches for modeling meteorologically sensitive container water dynamics have been limited. This study introduces the Water Height and Temperature in Container Habitats Energy Model (WHATCH'EM), a state-of-the-science, physically based energy balance model of water height and temperature in containers that may serve as development sites for mosquitoes. The authors employ WHATCH'EM to model container water dynamics in three cities along a climatic gradient in México ranging from sea level, where is highly abundant, to ~2100 m, where is rarely found.

Potential of neem (Azadirachta indica L.) for prevention and treatment of oncologic diseases.

Throughout time, plants have often displayed medicinal properties that have been underscored. We often derive medicines involved in treating cancer from components in plants. Azadirachta indica, commonly known as "neem", has been used to treat different ailments in many Asian countries.

It is estimated that 80% of the world population depends on traditional medicine for primary healthcare need. Trianthema portulacastrum Linn. (family: Aizoaceae) is a small perennial weed found in the Americas, Africa, India, and other regions of the world.

Pomegranate exerts chemoprevention of experimentally induced mammary tumorigenesis by suppression of cell proliferation and induction of apoptosis.

Breast cancer is the second leading cause of cancer-related death in women in the United States and discovery and development of safe chemopreventive drugs is urgently needed. The fruit pomegranate (Punica granatum) is gaining importance because of its various health benefits. This study was initiated to investigate chemopreventive potential of a pomegranate emulsion (PE) against 7,12-dimethylbenz(a)anthracene (DMBA) rat mammary carcinogenesis.

Community level risk factors for maternal mortality in Madagascar.

This paper explores the effect of risk and socioeconomic factors on maternal mortality at the community level in Madagascar using a unique, nationwide panel of communes (i.e., counties).

Ocimum sanctum Linn. (Tulsi): an ethnomedicinal plant for the prevention and treatment of cancer.

Ocimum sanctum Linn., commonly known as 'Tulsi' or 'Holy Basil', is considered to be the most sacred herb of India. Several anatomical parts of O.

Piezoelectric load measurement model in knee implants.

This paper explores the feasibility of a new sensing platform for knee implant diagnostics. The proposed unit measures force and transmits the reading information wirelessly to an external receiving unit. This device is to be located in the tibial tray of the knee implant.

Preparation of hollow magnetite microspheres and their applications as drugs carriers.

Hollow magnetite microspheres have been synthesized by a simple process through a template-free hydrothermal approach. Hollow microspheres were surface modified by coating with a silica nanolayer. Pristine and modified hollow microparticles were characterized by field-emission electron microscopy, transmission electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, FT-IR and Raman spectroscopy, and VSM magnetometry.

An alternative route for the synthesis of silicon nanowires via porous anodic alumina masks.

Amorphous Si nanowires have been directly synthesized by a thermal processing of Si substrates. This method involves the deposition of an anodic aluminum oxide mask on a crystalline Si (100) substrate. Fe, Au, and Pt thin films with thicknesses of ca.

Powering biomedical devices with body motion.

Energy harvesting from body motion is an alternative power source that can be used to energize miniature electronic biomedical devices. This technology can make it possible to recharge batteries to reduce the frequency of or eliminate surgeries to replace depleted cells. Power availability evaluation from walking and running at several body locations and different speeds is presented.

Energy scavenging sources for biomedical sensors.

Energy scavenging has increasingly become an interesting option for powering electronic devices because of the almost infinite lifetime and the non-dependence on fuels for energy generation. Moreover, the rise of wireless technologies promises new applications in medical monitoring systems, but these still face limitations due to battery lifetime and size. A trade-off of these two factors has typically governed the size, useful life and capabilities of an autonomous system.

Degradation of phenol by mechanical activation of a rutile catalyst.

In the present paper a novel mechanochemical process for the elimination of organic pollutants dissolved in water is proposed. In this regard, phenol aqueous solutions (100mgL(-1)) were ball-milled for 0, 12, 18, 24, 36, 48, and 72h with and without a well-characterized (XRD, SEM, and N(2) Adsorption), rutile powder catalyst and the reaction products analyzed with UV and GC/MS. It was found that when the catalyst was not included in the process, phenol was not affected, but when it was included, phenol was decomposed.

Paranitrophenol liquid-phase adsorption in dealuminated Y zeolite.

Was studied the liquid-phase paranitrophenol (PNP) dynamic adsorption in a packed bed adsorption reactor (PBAR), filled with dealuminated Y zeolite (DAY) and granulated active carbon (GAC). In addition, was measured the equilibrium maximum amount of adsorption for the system: PNP aqueous solution-DAY zeolite, at 300 K, to compare it with other adsorbents. The DAY zeolite and the GAC were characterized with adsorption methods.

Emission frequency modulation by electronic confinement effect: Congo Red incorporated within a dendritic structure.

We have investigated the photophysical properties of an organic dye (Congo Red) incorporated within the internal cavities of a dendrimer (type polypropylenimine of fifth-generation modified with a dense shell of amino acids). In this paper we show that the luminescence properties of Congo Red encapsulated into the "dendritic box" can be modulated by the electronic confinement effect. The emission frequencies of this organic dye incorporated within the dendritic structure can be red shifted with respect to their emission in solution, and the magnitude of this shifting can be modulated under appropriate experimental conditions.

Modulation of the photophysical properties of C60 by electronic confinement effect.

This research work reports on the incorporation of fullerene C60 in diverse inorganic and organic matrixes and how these different environments induce changes on the photophysical properties of the molecule depending on the cavity dimensions of the host. Indeed the fluorescence emission band of C60 experiences a progressive bathochromic shift with respect to C60 in solution as the cavity dimensions of the host decrease in going from the mesoporous material MCM41 to UTD-1 and Na-Y zeolites. This experimental observation, which has been documentarily confirmed by theoretical predictions and recent experimental results, is a reflection of the confinement effect imposed by the host.
