The neuroprotective efficacy and safety of Cistanche tubulosa extract (CTE) in reducing tauopathy levels were studied. However, evidence-based insights into how CTE enhances memory ability remain unclear. A total of 85 healthy volunteers (with MMSE scores ≥ 24, which is Normal/No impairment) participated in a double-blind, randomized, placebo-controlled study. Participants were assigned to one of three groups: Group A (600 mg CTE), Group B (300 mg CTE), or Group C (placebo), administere...

This study investigates the gastropod diversity, relative abundance, and distribution pattern of the gastropods present in Dapya Island, Barangay Day-asan Surigao del Norte, Philippines. The sampling was done 2 - 3 days during the lowest low tide at daytime employing the transect-quadrat method and established three sampling stations. A total of 496 individuals distributed among 12 genera and 25 species of gastropods were identified in the study area during the sampling period. The three most ab...

For several decades, many households in rural areas have relied on surrounding forests for their livelihoods, safety nets and sustenance. This reliance is most often determined by the household’s characteristics, available forests and economic benefits. That notwithstanding, the demand for more farmlands and unsustainable harvesting of forest resources are pushing these forests into depletion. This rapid decline endangers the livelihoods of forest-reliant households, threatens biodiversity and i...

The human history has recorded that in every 100 years a new pandemic will erupt to rocked control the human race from over population, changing the courses of history and signaling the end of entire civilization. Today the world is at halt and its economic, socio-cultural, religious, political, scientific and technological myth is degenerating amidst the advent of a novel pandemic (COVID-19). This study therefore, investigated the effect of COVID-19 in terms of economic, socio-cultural, educati...

Zonal and height belts
differentiation of environmental parameters determine forms and types of
changes during formation of systems of any natural hierarchy. Under climatic
conditions, when shifts of environmental (geographic) zones or height belts as
definite environments is possible, there are processes able to result in
structural differentiation of the whole biosphere. The problem of fores ...

Mapping of forest vegetation is considered as an
efficient method for obtaining of statistic information, which serves as a base
for determination of the character of coenisis use in concrete regions.
Different scales and periodicity of vegetation mapping allow to establish the
peculiarities of coenisis structure, dynamics and functioning. Physical-geographic
conditions pre-determine time intervals of forests taxat ...

At the territories of
three key sites with different environmental conditions (coast of Irkutsk
Reservoir, the Goloustnaya River basin, surroundings of Gakhany settlement in60 kmnorthward from the
urbanized area Ust’-Orda, Irkutsk Region), we performed studies aimed to reveal
the structural-dynamic organization and trends of forests reconstitution at the
places of burnt areas and of cuttings of different targets. We took into acco ...

Within investigations for project and establishing
of a coal mine, preliminary survey aimed to revealing of modern state of vegetation at the
territory of establishing of projected coal mine was performed. The information
of the structure of phytocenoses modern state can be a reference position for
the assessment of a possible impact of technical activities on the state of
phytocenoses around ...

Setting of forms and methods for forest use must be
based on assessment and forecast characteristics of forests modern state taking
into account probable trends of their formation (or reconstitution) on the base
of the analysis of modern physical-geographic conditions on a concrete
territory. A very efficient method for this can be an ecological mapping
monitoring of forest use with outlining of a series of ecological-geobotanic
m ...

Usage of methods for determination of long-time
trends in the dynamics of vegetation formation on the background of climate
changes becomes more important at modern stage of the assessment of natural
systems development. Solution of such a task results inevitably in necessity to
correct the understanding of existing processes occurring in the vegetation
cover. It allows establishing a direction of their development in system of
na ...
