Unlike FASTQC, fastp samples all reads evenly to evaluate overrepresented sequences and eliminate partial distribution bias. To achieve an efficient implementation of this feature, we designed a two-step method. In the first step, fastp completely analyzes the first 1.5 M base pairs of the input FASTQ to obtain a list of sequences with relatively high occurrence frequency in different sizes. In the second step, fastp samples the entire file and counts the occurrence of each sequence. Finally, the sequences with high occurrence frequency are reported.
Besides the occurrence frequency, fastp also records the positions of overrepresented sequences. This information is quite useful for diagnosing sequence quality issues. Some sequences tend to appear in the read head whereas others appear more often in the read tail. The distribution of overrepresented sequences is visualized in the HTML report.

Example 3
Reactivity of the antibodies of the invention against several species of mesothelin (cyno, rat, mouse) was tested using assays well known in the art. The data is summarized in
FACS binding assays were performed to evaluate the binding of the anti-Mesothlelin antibodies to murine, rat and cynomologous monkey mesothelin orthologues, using recombinant forms of the various receptors transiently expressed on 293T cells. FACs assays were performed by incubating hybridoma supernatants with 10,000 to 25,000 cells in PBS/2% Fetal bovine serum/2 mM Calcium Chloride at 4° C. for one hour followed by two washes with PBS/2% Fetal bovine serum/2 mM Calcium Chloride. Cells were then treated with florochrome-labeled secondary antibodies at 4° C. followed by one wash. The cells were resuspended in 50 μl of PBS/2% FBS and antibody binding was analyzed using a FACSCalibur™ instrument.

Reagents
-
- 0.14M NaF solution
- Absolute (100%) ethanol
- tetraethyl orthosilicate (TEOS, (Si(OC2H5)4))
- Brushite (CaHPO4·2H2O) Brushite is dissolved in 0.14 M solution of NaF, after which ethanol is added. This mixture is then stirred for 5 minutes.
Finally the TEOS is combined slowly with the solution and is allowed to stir for thirty seconds.
4 ml of the solution is cast into cylindrical moulds (Ø11 mm×50 mm height, via syringe). Each mould is then covered with film and placed into glass container.
Each sample is then gelled for 48 hours at 60° C.
Each sample is then placed into 60% ethanol. After 24 hours the solution is changed for 80% ethanol. After another 24 hours it is changed once again for 95% ethanol. Finally the solution is replaced with 100% ethanol.
Each sample is dried using the CPD method using a Tousimis® 931 critical point drier. Each sample is run through three stasis cycles of eight hours each.
After critical drying each sample is then calcined at 700° C. for three hours.

Example 12
As a proof of concept, the patient population of this study is patients that (1) have moderate to severe ulcerative colitis, regardless of extent, and (2) have had an insufficient response to a previous treatment, e.g., a conventional therapy (e.g., 5-ASA, corticosteroid, and/or immunosuppressant) or a FDA-approved treatment. In this placebo-controlled eight-week study, patients are randomized. All patient undergo a colonoscopy at the start of the study (baseline) and at week 8. Patients enrolled in the study are assessed for clinical status of disease by stool frequency, rectal bleeding, abdominal pain, physician's global assessment, and biomarker levels such as fecal calprotectin and hsCRP. The primary endpoint is a shift in endoscopy scores from Baseline to Week 8. Secondary and exploratory endpoints include safety and tolerability, change in rectal bleeding score, change in abdominal pain score, change in stool frequency, change in partial Mayo score, change in Mayo score, proportion of subjects achieving endoscopy remission, proportion of subjects achieving clinical remission, change in histology score, change in biomarkers of disease such as fecal calprotectin and hsCRP, level of adalimumab in the blood/tissue/stool, change in cytokine levels (e.g., TNFα, IL-6) in the blood and tissue.
For example, treatment for a patient that is diagnosed with ulcerative colitis is an ingestible device programmed to release a single bolus of a therapeutic agent, e.g., 40 mg adalimumab, in the cecum or proximal to the cecum. Prior to administration of the treatment, the patient is fasted overnight and is allowed to drink clear fluids. Four hours after swallowing the ingestible device, the patient can resume a normal diet. An ingestible device is swallowed at the same time each day. The ingestible device is not recovered.
In some embodiments, there may be two different ingestible devices: one including an induction dose (first 8 to 12 weeks) and a different ingestible device including a different dose or a different dosing interval.
In some examples, the ingestible device can include a mapping tool, which can be used after 8 to 12 weeks of induction therapy, to assess the response status (e.g., based on one or more of the following: drug level, drug antibody level, biomarker level, and mucosal healing status). Depending on the response status determined by the mapping tool, a subject may continue to receive an induction regimen or maintenance regimen of adalimumab.
In different clinical studies, the patients may be diagnosed with Crohn's disease and the ingestible devices (including adalimumab) can be programmed to release adalimumab in the cecum, or in both the cecum and transverse colon.
In different clinical studies, the patients may be diagnosed with illeocolonic Crohn's disease and the ingestible devices (including adalimumab) can be programmed to release adalimumab in the late jejunum or in the jejunum and transverse colon.
Example 2
The next experiments asked whether inhibition of the same set of FXN-RFs would also upregulate transcription of the TRE-FXN gene in post-mitotic neurons, which is the cell type most relevant to FA. To derive post-mitotic FA neurons, FA(GM23404) iPSCs were stably transduced with lentiviral vectors over-expressing Neurogenin-1 and Neurogenin-2 to drive neuronal differentiation, according to published methods (Busskamp et al. 2014, Mol Syst Biol 10:760); for convenience, these cells are referred to herein as FA neurons. Neuronal differentiation was assessed and confirmed by staining with the neuronal marker TUJ1 (
It was next determined whether shRNA-mediated inhibition of FXN-RFs could ameliorate two of the characteristic mitochondrial defects of FA neurons: (1) increased levels of reactive oxygen species (ROS), and (2) decreased oxygen consumption. To assay for mitochondrial dysfunction, FA neurons an FXN-RF shRNA or treated with a small molecule FXN-RF inhibitor were stained with MitoSOX, (an indicator of mitochondrial superoxide levels, or ROS-generating mitochondria) followed by FACS analysis.
Mitochondrial dysfunction results in reduced levels of several mitochondrial Fe-S proteins, such as aconitase 2 (ACO2), iron-sulfur cluster assembly enzyme (ISCU) and NADH:ubiquinone oxidoreductase core subunit S3 (NDUFS3), and lipoic acid-containing proteins, such as pyruvate dehydrogenase (PDH) and 2-oxoglutarate dehydrogenase (OGDH), as well as elevated levels of mitochondria superoxide dismutase (SOD2) (Urrutia et al., (2014) Front Pharmacol 5:38). Immunoblot analysis is performed using methods known in the art to determine whether treatment with an FXN-RF shRNA or a small molecule FXN-RF inhibitor restores the normal levels of these mitochondrial proteins in FA neurons.
