Errors and Limitaions of Next Generation SequencingNixon Mendez
High throughput sequencing technologies has made whole genome sequencing and resequencing available to many more researchers and projects.
Cost and time have been greatly reduced.
The error profiles and limitations of the new platforms differ significantly from those of previous sequencing technologies.
The selection of an appropriate sequencing platform for particular types of experiments is an important consideration.
NGS sequencing errors focuses mainly on the following points:
1.Low quality bases
2.PCR errors
3.High Error rate
NGS has inherent limitations they are as follows :
1.Sequence properties and algorithmic challenges
2.Contamination or new insertions
3.Repeat content
4.Segmental duplications
5.Missing and fragmented genes
6.Reference index
Viral metagenomics is the study of viral genetic material sourced directly from the environment rather than from a host or natural reservoir. The goal is to ascertain the viral diversity in the environment that is often missed in studies targeting specific potential reservoirs.

Metagenomics is the study of metagenomes, genetic material recovered directly from environmental samples. The broad field was referred to as environmental genomics, ecogenomics or community genomics. Recent studies use "shotgun" Sanger sequencing or next generation sequencing (NGS) to get largely unbiased samples of all genes from all the members of the sampled communities.
K-mers in metagenomics
K-mers play a critical role in the exploration of metagenomic data. They have been widely used to assign taxonomic attributions to the short genomic fragments characteristic of shotgun (metagenomic) sequencing. These approaches provide an assembly-free method for profiling microbial communities, and have helped elucidate the factors driving microbial community composition across biogeochemical gradients. Advances in sequencing technology are now making it cost-effective to sequence microbial communities at sufficient depths to allow for the assembly of high-quality contigs. This has made it possible to adopt k-mer based approaches to enable reliable binning of contigs originating from a single microbial population within a community. In this session, I will present both an overview of how k-mers can be used to assign taxonomic attributions to short metagenomic reads, and discuss how these approaches have advanced to a point where population genomes can be recovered en masse from even complex microbial communities.
With decades of experience in the fields of genomics sequencing, CD Genomics is devoted to providing unprecedented amounts of microbial metatranscriptomic data. Our strong expertise in the informative and unbiased metatranscriptomic sequencing service is guaranteed by state-of-the-art high throughput sequencers, flexible sequencing strategies, and professional bioinformatics pipelines.

Genomic Cytometry: Using Multi-Omic Approaches to Increase Dimensionality in ...Robert (Rob) Salomon
"Genomic Cytometry: Using Multi-Omic Approaches to Increase Dimensionality in Cytometry" was an Invited Tutorial given at the 2019 CYTO conference for the the International Society for the Advancement of Cytometry on the 22nd May 2019. This tutorial was recorded and we expect that it will be converted to a CYTOU webinar in the near future.
This tutorial will begin by explaining why the emerging field of Genomic Cytometry, i.e. the measurement of cells using genomic techniques (e.g. sequencing), in conjunction with more traditional cytometry techniques such as fluorescence, mass and imaging cytometry is becoming a standard tool for biologists looking to unravel complex cellular processes and to develop a deeper understanding of heterogeneity.
We will give a detailed overview of the various technologies that have allowed the emergence of Genomic Cytometry as well as those that continue to push the boundaries of cellular characterisation.
We will then provide a basic overview of the sequencing process such that both research cytometerists and the staff for the cytometry SRL are better equipped to understand the downstream genomic component of Genomic Cytometry.
Finally, we will wrap up the session with case studies that illustrate the power of the genomic cytometry approach and will give a brief outline of where we feel the field needs to go as it matures. We expect attendees will gain a better understanding of 1) the rapidly maturing field of Genomic Cytometry and 2) how Genomic Cytometry should be leveraged into more traditional cytometry workflows.
A micro-array is a tool for analyzing gene expression that consists of a small membrane or glass slide containing samples of many genes arranged in a regular pattern.
This was made by me while I was in Masters. I have made few animations. I hope it makes understanding better.
The content is made by searching through internet and referencing books. I do not claim any content in whole presentation except the animations made on the subject.

Increased number of fungiform papillae
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
